# 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 or release builds, for example
#
#   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.
#
# - Say `cmake -LAH` to see all configuration options.
#
# - `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_REQUIRE_ZLIB', `FT_REQUIRE_BZIP2', `FT_REQUIRE_PNG',
#   `FT_REQUIRE_HARFBUZZ', and `FT_REQUIRE_BROTLI' CMake variables to `ON'
#   or `TRUE' 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_REQUIRE_ZLIB=TRUE \
#                    -D FT_REQUIRE_BZIP2=TRUE \
#                    -D FT_REQUIRE_PNG=TRUE \
#                    -D FT_REQUIRE_HARFBUZZ=TRUE \
#                    -D FT_REQUIRE_BROTLI=TRUE [...]
#
# - Set `FT_DISABLE_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 FT_DISABLE_ZLIB=TRUE \
#                    -D FT_DISABLE_BZIP2=TRUE \
#                    -D FT_DISABLE_PNG=TRUE \
#                    -D FT_DISABLE_HARFBUZZ=TRUE \
#                    -D FT_DISABLE_BROTLI=TRUE [...]
#
# - NOTE: If a package is set as DISABLED, it cannot be set as REQUIRED
#   without unsetting the DISABLED value first.  For example, if
#   `FT_DISABLE_HARFBUZZ=TRUE' has been set (Cache is present), you need to
#   call `FT_DISABLE_HARFBUZZ=FALSE' before calling
#   `FT_REQUIRE_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).

# To minimize the number of cmake_policy() workarounds,
# CMake >= 3 is requested.
