* FindGit: remove EasyGitMichael Hirsch2022-04-111-3/+3
| | | | | | | | | | Blame shows EasyGit was part of initial FindGit 11 years ago. I can hardly find Easy Git as a package. Given that Git is vital for many complex CMake projects, it seems good to ensure CMake FindGit is finding a Git program likely to work. Crucial CMake modules like FetchContent also use FindGit, emphasizing the importance of having a Git executable with proper functionality.
* FindGit: Cache the version more effectivelyCraig Scott2021-02-051-16/+17
| | | | | | | | | | | | In 315a200f0c4 (FindGit: Cache the GIT_EXECUTABLE version for the current run, 2021-01-20), the GIT_VERSION_STRING was meant to be cached after the first time it was computed for a given GIT_EXECUTABLE location. That logic assumed GIT_VERSION_STRING would be visible in the current scope, but it might not be. The global property alone is enough to check whether the version has been determined previously, so don't switch the logic based on whether GIT_VERSION_STRING is defined or not. Relates: #21703
* FindGit: Cache the GIT_EXECUTABLE version for the current runCraig Scott2021-01-201-7/+37
| | | | | | | | | | | The git version should not change while CMake is running. When using FetchContent with many dependencies, the repeated calls to get the git version every time ExternalProject is used can be measurable on some platforms. This commit queries that version only once and then caches it in a global property for the rest of that run. The git version can still safely change between runs because it is not cached, only the GIT_EXECUTABLE location is cached. Relates: #21703

* FindGit: Avoid finding VS 2017 non-general Git installationBrad King2017-03-101-1/+15
| | | | | | | | | | | At a VS 2017 command prompt the `PATH` contains a directory that happens to have a `Git/cmd/git.exe` inside it. However, this executable is not meant for general use. Revise our use of `Git/` path suffixes to be more specific to its original purpose of searching in the typical `c:/Program Files*/Git/` installation directories. Avoid using the suffixes on `PATH` entries. Fixes: #16706

* Simplify CMake per-source license noticesBrad King2016-09-271-14/+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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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.
* FindGit: Add new 'GitHub for Windows' user directoryFrank Park2016-04-151-2/+4
| | | | | | | | | | | | | GitHub for Windows now installs in $ENV{LOCALAPPDATA}/Github/PortableGit*/cmd instead of $ENV{LOCALAPPDATA}/Github/PortableGit*/bin Search the new location first but keep the old one in case people have older versions installed.

* 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

* 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.

* Add FindGit module.David Cole2010-06-031-0/+46
Use it from ExternalProject and the ExternalProject test's CMakeLists file rather than having duplicate find_program calls. Add logic so that we do not try to use *.cmd variants of git programs when using the MSYS Makefiles generator. Should fix the last remaining dashboard issue with the new ExternalProject git support additions. Also, correct minor problem regarding placement of the local git repo during test execution. On clean builds, it was being placed incorrectly because of the ../.. relative reference. Use an absolute path to place the local git repo in the proper directory, and only use the relative reference when referring to it.
