To build GD using CMake, all you need is (add the cmake options if you need any
or if the default libs and include paths are not the default) :
In a sub directory of the top level:
$ mkdir bld
$ cd bld
$ cmake -DBUILD_TEST=1 <options> ..
$ make
The available options are:
ENABLE_GD_FORMATS=1
ENABLE_PNG=1
ENABLE_LIQ=1
ENABLE_JPEG=1
ENABLE_TIFF=1
ENABLE_ICONV=1
ENABLE_FREETYPE=1
ENABLE_FONTCONFIG=1
ENABLE_XPM=1
ENABLE_WEBP=1
ENABLE_AVIF=1
ENABLE_RAQM=1
You can optionally run our tests suite using:
$ ctest .
Or if you like to build in the source tree:
$ cmake -DBUILD_TEST=1 .
$ make
$ ctest .
Add "-DCMAKE_BUILD_TYPE=DEBUG" if you like to have a debug version.
To install, just run:
$ make install
Or to to install to a different path:
$ make install DESTDIR=/some/other/place
Typical usage with only PNG enabled:
This command generates VS7 project files and add some custom libraries and
includes directories (libpng in this case):
cmake -DCMAKE_GENERATOR="Visual Studio 7 .NET 2003"
-DENABLE_PNG=1 -DCMAKE_LIBRARY_PATH=c:\gd_build\gd_deps\lib
-DCMAKE_INCLUDE_PATH=c:\gd_build\gd_deps\include c:\libgd_src
A typical CMake call to build using the MinGW tools:
cmake -G"MinGW Makefiles" -DCMAKE_LIBRARY_PATH=c:\mingw\lib -DCMAKE_INCLUDE_PATH=c:\MinGW\include -DENABLE_JPEG=On -DBUILD_TEST=On -DCMAKE_RELEASE_TYPE=DEBUG ..\libgd_head
Given that your MinGW install is under c:\mingw and that you install all libraries using the /usr prefix
vcpkg support add dependencies and library on Windows (or Linux/Mac/etc)
------------------------------------------------------------------------
Inside the development console, in the desired mode (see https://docs.microsoft.com/en-us/cpp/build/building-on-the-command-line?view=msvc-160), to install
the required libraries, vcpkg can install them automatically. The steps are:
1. Install vcpkg, see https://vcpkg.io/en/getting-started.html
2. Choose the vcpkg architecture
SET VCPKG_DEFAULT_TRIPLET=x64-windows (or add pkgname:x64-windows)
3. install the dependencies needed for the build. F.e.
C:\vcpkg\vcpkg.exe install libpng libjpeg-turbo freetype tiff libheif libwebp
4. add -DCMAKE_TOOLCHAIN_FILE=[path to c:\path\to\vcpkg]\scripts\buildsystems\vcpkg.cmake
with the other desired cmake options
It is then not needed to manually add CMAKE_INCLUDE_PATH or CMAKE_LIBRARY_PATH as options.
See the https://vcpkg.io for more informations about vcpkg and how to customize an install.
Randomly, you may cmake may fail to find the dependencies, with vcpkg at least up to 2021-08-12-85ab112d5ee102bc6eac8cdbbfdd173a71374e04 (as of the time of writing).
So far the only way to fix it is to reinstall vcpkg and then install the dependencies again. See https://github.com/microsoft/vcpkg/issues/13614,
especially my comment on the 27th of August 2021 and follow ups.
