- # The following will 1. create a build directory and 2. change into it and
- # call cmake to configure the build with default parameters as a static
- # library.
- #
- # cmake -E make_directory build
- # cmake -E chdir build cmake ..
- #
- # For a dynamic library, use
- #
- # cmake -E chdir build cmake -D BUILD_SHARED_LIBS:BOOL=true ..
- #
- # For a framework on OS X, use
- #
- # cmake -E chdir build cmake -G Xcode -D BUILD_FRAMEWORK:BOOL=true ..
- #
- # For an iOS static library, use
- #
- # cmake -E chdir build cmake -G Xcode -D IOS_PLATFORM=OS ..
- #
- # or
- #
- # cmake -E chdir build cmake -G Xcode -D IOS_PLATFORM=SIMULATOR ..
- #
- # or
- #
- # cmake -E chdir build cmake -G Xcode -D IOS_PLATFORM=SIMULATOR64 ..
- #
- # Finally, build the project with:
- #
- # cmake --build build
- #
- # Install it with
- #
- # (sudo) cmake --build build --target install
- #
- # A binary distribution can be made with
- #
- # cmake --build build --config Release --target package
- #
- # Please refer to the cmake manual for further options, in particular, how
- # to modify compilation and linking parameters.
- #
- # Some notes.
- #
- # . `cmake' creates configuration files in
- #
- # <build-directory>/include/freetype/config
- #
- # which should be further modified if necessary.
- #
- # . You can use `cmake' directly on a freshly cloned FreeType git
- # repository.
- #
- # . `CMakeLists.txt' is provided as-is since it is normally not used by the
- # developer team.
- #
- # . Set the `FT_WITH_ZLIB', `FT_WITH_BZIP2', `FT_WITH_PNG', and
- # `FT_WITH_HARFBUZZ' CMake variables to `ON' to force using a dependency.
- # Leave a variable undefined (which is the default) to use the dependency
- # only if it is available. Set `CMAKE_DISABLE_FIND_PACKAGE_HarfBuzz=TRUE' to
- # disable a dependency completely (CMake package name, so `BZip2' instead of
- # `BZIP2'). Example:
- #
- # cmake -DFT_WITH_ZLIB=ON -DCMAKE_DISABLE_FIND_PACKAGE_HarfBuzz=TRUE [...]
- #
- # . Installation of FreeType can be controlled with the CMake variables
- # `SKIP_INSTALL_HEADERS', `SKIP_INSTALL_LIBRARIES', and `SKIP_INSTALL_ALL'
- # (this is compatible with the same CMake variables in zlib's CMake
- # support).
- # FreeType explicitly marks the API to be exported and relies on the compiler
- # to hide all other symbols. CMake supports a C_VISBILITY_PRESET property
- # starting with 2.8.12.
