* Find{BZip2,LibLZMA,ZLIB}: use *_VERSION as modern CMakeMichael Hirsch2022-11-071-20/+46
| | | | The old *_VERSION_STRING is silently left set for backward compat.
* FindZLIB: Fail if components are requested as it does not provide anykoostosh2022-10-121-1/+10
| | | | Fixes: #18872
* FindZLIB: fix CMAKE_FIND_LIBRARY_PREFIXES being unset when it was emptyDaniel Scharrer2022-09-061-4/+20
| | | | | | | | | | | | | | | | | | | CMAKE_FIND_LIBRARY_PREFIXES and CMAKE_FIND_LIBRARY_SUFFIXES have different behavior when undefined and when defined but empty: Empty means to use an empty prefix/suffix while undefined means to use a hardcoded default for the platform we are running on. Unfortunately, set(a ${b}) will undefine a when b is empty, meaning that when targeting a platform where either of these variables is empty (e.g. Windows where CMAKE_FIND_LIBRARY_PREFIXES is empty) the unpatched FindZLIB code ends up unsetting that variable, causing all subsequent find_library calls to use the hardcoded default for the runtime platform (e.g. "lib" for CMAKE_FIND_LIBRARY_PREFIXES on Linux). On the other hand, set(a "${b}") will always define a to be empty but defined so we have to do this dance to fully preserve the state of these variables.
* FindZLIB: fix ZLIB_USE_STATIC_LIBS on WindowsPeter Würth2022-05-131-6/+16
| | | | | | | | | | - on Windows, the ZLIB_USE_STATIC_LIBS options requires a reordering of the search names in order to prefer the static library, since in most cases both static and shared libraries are built - add zlibwapi[d] library name for the contrib/vstudio builds - add lib prefix and .dll.a suffix for the win32/Makefile.gcc build Fixes #23140
* FindZLIB: more library names + option to prefer static libraryPeter Würth2022-03-121-2/+22
| | | | | | | | | | | Adds additional library names `zlibstat[d]` and `zlibvc[d]` for Windows, when zlib is built using one of the Visual Studio solutions under `zlib/contrib/vstudio`. Adds a `ZLIB_USE_STATIC_LIBS` option that is equivilent to similar settings in other modules such as FindProtobuf, FindOpenSSL, etc. Implements #18029 and #23140
* Help: Add `.. versionadded` directives to module docsNikita Nemkin2020-12-021-0/+5

* FindZLIB: Add more zlib library namesAlexander Neumann2019-05-281-2/+2
| | | | | | | Account for all names that can be generated by the upstream zlib build system. Issue: #18029

* FindZLIB: Search names per directoryStefan Hacker2018-02-151-2/+2
| | | | | | | | | | | | | | | | | | | | | FindZLIB accepts various names for zlib (e.g. "z", "zlib", ...) in various search locations. Before this patch zlib ignored the priority implied by the search locations and instead prioritized based on the library name. Consequently ensuring the pick of a zlib from e.g. a CMAKE_PREFIX_PATH was not possible if it didn't have the highest priority name ("z"). This unexpected behavior led to bugs in third party projects (e.g. https://github.com/Microsoft/vcpkg/issues/1939). A common way to encounter the issue in the wild is on Windows with the popular Anaconda python distribution which puts a "z.lib" in a lib/ subdirectory reachable from a bin/ path in PATH. From then on cmake will always pick up this library instead of the one intended by the user. This patch adds the NAMES_PER_DIR option to the find_library calls made by FindZLIB making it search each directory for all names before considering lower priority directory names resolving these issues.
* Find*.cmake: drop the comments before including FPHSARolf Eike Beer2016-11-281-2/+0
| | | | | No need to explain this over and over again. While at it, do some other minor cleanups to whitespace and comments (i.e. delete them).
* Simplify CMake per-source license noticesBrad King2016-09-271-13/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Per-source copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong. Precise contributor information is already maintained automatically by the version control tool. Ultimately it is the receiver of a file who is responsible for determining its licensing status, and per-source notices are merely a convenience. Therefore it is simpler and more accurate for each source to have a generic notice of the license name and references to more detailed information on copyright holders and full license terms. Our `Copyright.txt` file now contains a list of Contributors whose names appeared source-level copyright notices. It also references version control history for more precise information. Therefore we no longer need to spell out the list of Contributors in each source file notice. Replace CMake per-source copyright/license notice headers with a short description of the license and links to `Copyright.txt` and online information available from "https://cmake.org/licensing". The online URL also handles cases of modules being copied out of our source into other projects, so we can drop our notices about replacing links with full license text. Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority of the replacements mechanically. Manually fix up shebang lines and trailing newlines in a few files. Manually update the notices in a few files that the script does not handle.
* Use string(APPEND) in ModulesDaniel Pfeifer2016-07-281-1/+1
| | | | | | | Automate with: find Modules -type f -print0 | xargs -0 perl -i -0pe \ 's/set\(([a-zA-Z0-9_]+)(\s+)"\$\{\1\}([^"])/string(APPEND \1\2"\3/g'
* FindZLIB: Do not mark unused variable as advancedBrad King2016-06-211-1/+1
| | | | | | | We no longer define the ZLIB_LIBRARY cache entry, so we should not mark it as advanced either. We only use this variable when someone else defines it in order to remain compatible with older versions of this module, but we never create the entry ourselves anymore.
* FindZLIB: Find debug and release variants separatelyMichael Scott2015-09-021-5/+40
| | | | | | Provide each variant in ZLIB_LIBRARIES and ZLIB::ZLIB imported location properties when one is found, while maintaining support for manually setting the library via ZLIB_LIBRARY.

* Remove .* expressions from beginning and end of MATCHES regexsRolf Eike Beer2014-04-141-1/+1
| | | | | | | | | All these expressions work the same: "foo" ".*foo.*" "^.*foo.*$" This assumes that the "Intel*" expressions were meant to be "Intel.*".
* Convert builtin help to reStructuredText source filesKitware Robot2013-10-151-16/+32
| | | | | | | | Run the convert-help.bash script to convert documentation: ./convert-help.bash "/path/to/CMake-build/bin" Then remove it.
* Remove CMake-language block-end command argumentsKitware Robot2012-08-131-1/+1
| | | | | | | | | | | | | | | | | Ancient versions of CMake required else(), endif(), and similar block termination commands to have arguments matching the command starting the block. This is no longer the preferred style. Run the following shell code: for c in else endif endforeach endfunction endmacro endwhile; do echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/' done >convert.sed && git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' | egrep -z -v '^(Utilities/cm|Source/kwsys/)' | egrep -z -v 'Tests/CMakeTests/While-Endwhile-' | xargs -0 sed -i -f convert.sed && rm convert.sed
* Convert CMake-language commands to lower caseKitware Robot2012-08-131-33/+33
| | | | | | | | | | | | | | | | | Ancient CMake versions required upper-case commands. Later command names became case-insensitive. Now the preferred style is lower-case. Run the following shell code: cmake --help-command-list | grep -v "cmake version" | while read c; do echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g' done >convert.sed && git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' | egrep -z -v '^(Utilities/cm|Source/kwsys/)' | xargs -0 sed -i -f convert.sed && rm convert.sed
* Remove trailing whitespace from most CMake and C/C++ codeKitware Robot2012-08-131-1/+1
| | | | | | | | | | | | | | | | | Our Git commit hooks disallow modification or addition of lines with trailing whitespace. Wipe out all remnants of trailing whitespace everywhere except third-party code. Run the following shell code: git ls-files -z -- \ bootstrap doxygen.config '*.readme' \ '*.c' '*.cmake' '*.cpp' '*.cxx' \ '*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \ '*.mm' '*.pike' '*.py' '*.txt' '*.vim' | egrep -z -v '^(Utilities/cm|Source/(kwsys|CursesDialog/form)/)' | egrep -z -v '^(Modules/CPack\..*\.in)' | xargs -0 sed -i 's/ \+$//'
* FindZLIB: Search under ZLIB_ROOT if it is setBrad King2011-11-301-10/+25
| | | | | | | | | | Perform multiple separate searches in order. If ZLIB_ROOT is set search it exclusively so it takes precedence over CMAKE_PREFIX_PATH. This allows a user to provide -DZLIB_ROOT=/path/to/zlib/prefix on the CMake command line to tell it exactly where to find zlib. Otherwise fall back to a normal search.

* Modules: Include builtin FindPackageHandleStandardArgs directlyBrad King2011-01-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The FindPackageHandleStandardArgs module was originally created outside of CMake. It was added for CMake 2.6.0 by commit e118a627 (add a macro FIND_PACKAGE_HANDLE_STANDARD_ARGS..., 2007-07-18). However, it also proliferated into a number of other projects that at the time required only CMake 2.4 and thus could not depend on CMake to provide the module. CMake's own find modules started using the module in commit b5f656e0 (use the new FIND_PACKAGE_HANDLE_STANDARD_ARGS in some of the FindXXX modules..., 2007-07-18). Then commit d358cf5c (add 2nd, more powerful mode to find_package_handle_standard_args, 2010-07-29) added a new feature to the interface of the module that was fully optional and backward compatible with all existing users of the module. Later commit 5f183caa (FindZLIB: use the FPHSA version mode, 2010-08-04) and others shortly thereafter started using the new interface in CMake's own find modules. This change was also backward compatible because it was only an implementation detail within each module. Unforutnately these changes introduced a problem for projects that still have an old copy of FindPackageHandleStandardArgs in CMAKE_MODULE_PATH. When any such project uses one of CMake's builtin find modules the line include(FindPackageHandleStandardArgs) loads the copy from the project which does not have the new interface! Then the including find module tries to use the new interface with the old module and fails. Whether this breakage can be considered a backward incompatible change in CMake is debatable. The situation is analagous to copying a standard library header from one version of a compiler into a project and then observing problems when the next version of the compiler reports errors in its other headers that depend on its new version of the original header. Nevertheless it is a change to CMake that causes problems for projects that worked with previous versions. This problem was discovered during the 2.8.3 release candidate cycle. It is an instance of a more general problem with projects that provide their own versions of CMake modules when other CMake modules depend on them. At the time we resolved this instance of the problem with commit b0118402 (Use absolute path to FindPackageHandleStandardArgs.cmake everywhere, 2010-09-28) for the 2.8.3 release. In order to address the more general problem we introduced policy CMP0017 in commit db44848f (Prefer files from CMAKE_ROOT when including from CMAKE_ROOT, 2010-11-17). That change was followed by commit ce28737c (Remove usage of CMAKE_CURRENT_LIST_DIR now that we have CMP0017, 2010-12-20) which reverted the original workaround in favor of using the policy. However, existing project releases do not set the policy behavior to NEW and therefore still exhibit the problem. We introduced in commit a364daf1 (Allow users to specify defaults for unset policies, 2011-01-03) an option for users to build existing projects by adding -DCMAKE_POLICY_DEFAULT_CMP0017=NEW to the command line. Unfortunately this solution still does not allow such projects to build out of the box, and there is no good way to suggest the use of the new option. The only remaining solution to keep existing projects that exhibit this problem building is to restore the change originally made in commit b0118402 (Use absolute path to FindPackageHandleStandardArgs.cmake everywhere, 2010-09-28). This also avoids policy CMP0017 warnings for this particular instance of the problem the policy addresses.

* Remove usage of CMAKE_CURRENT_LIST_DIR now that we have CMP0017Alex Neundorf2011-01-041-1/+1
| | | | | | | | This puts the new search behaviour for included files in action, i.e. now when a file from Modules/ include()s another file, it also gets the one from Modules/ included, i.e. the one it expects. Alex
* Use absolute path to FindPackageHandleStandardArgs.cmake everywhereAlex Neundorf2010-09-281-1/+1
| | | | | | | This is to avoid getting an (older) copy of FPHSA.cmake which is e.g. installed with KDE 4.5.0 and 4.5.1. Alex
* Fix ZLIB version parsing if no TWEAK version existsAlex Neundorf2010-08-141-2/+7
| | | | | | | | | | ZLIB_VERSION_STRING was "1.2.3.#define ZLIB_VERSION "1.2.3"" here, because the result of the matching for the tweak version was also appended if there was no TWEAK version and the regexp failed, which gives as result not an empty string, but the full string. Now it is only appended if the regexp matches. Alex

* FindZLIB: optimize zlib.h version parsingKovarththanan Rajaratnam2010-07-311-7/+39
| | | | | | Read zlib.h by using file(STRINGS.....REGEX) to limit the amount of text we apply the version regex on. This patch also addresses the fact that the version string may contain a tweak component. Patch by Simone Rossetto
* Fix performance issue with getting version from zlib.hClinton Stimpson2010-06-241-1/+1
| | | | | | | Some zlib.h files have ZLIB_VERSION "1.2.3.3" with 4 numbers instead of 3. The regex is changed to grab the first 3 numbers. It was slow because if it failed to find that string near the top of the file, where it usually is, it would read the entire file.
