# 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 ..
|
|
#
|
|
# 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.
