#
# 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. See https://cmake.org/cmake/help/latest/variable/CMAKE_BUILD_TYPE.html
# for information about Debug, Release, etc. builds.
#
# cmake -B build -D CMAKE_BUILD_TYPE=Release
#
# For a dynamic library, use
#
# cmake -B build -D BUILD_SHARED_LIBS=true -D CMAKE_BUILD_TYPE=Release
#
# 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',
# `FT_WITH_HARFBUZZ', and `FT_WITH_BROTLI' 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. Example:
#
# cmake -B build -D FT_WITH_ZLIB=ON \
# -D FT_WITH_BZIP2=ON \
# -D FT_WITH_PNG=ON \
# -D FT_WITH_HARFBUZZ=ON \
# -D FT_WITH_BROTLI=ON [...]
#
# Set `CMAKE_DISABLE_FIND_PACKAGE_XXX=TRUE' to disable a dependency completely
# (where `XXX' is a CMake package name like `BZip2'). Example for disabling all
# dependencies:
#
# cmake -B build -D CMAKE_DISABLE_FIND_PACKAGE_ZLIB=TRUE \
# -D CMAKE_DISABLE_FIND_PACKAGE_BZip2=TRUE \
# -D CMAKE_DISABLE_FIND_PACKAGE_PNG=TRUE \
# -D CMAKE_DISABLE_FIND_PACKAGE_HarfBuzz=TRUE \
# -D CMAKE_DISABLE_FIND_PACKAGE_BrotliDec=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.
