#   cmake CMakeLists.txt
#
# to create a Makefile that builds a static version of the library.
#
# For a dynamic library, use
#
#   cmake CMakeLists.txt -DBUILD_SHARED_LIBS:BOOL=true
#
# For a framework on OS X, use
#
#   cmake CMakeLists.txt -DBUILD_FRAMEWORK:BOOL=true -G Xcode
#
# instead.
#
# For an iOS static library, use
#
#   cmake CMakeLists.txt -DIOS_PLATFORM=OS -G Xcode
#
# or
#
#   cmake CMakeLists.txt -DIOS_PLATFORM=SIMULATOR -G Xcode
#
# Please refer to the cmake manual for further options, in particular, how
# to modify compilation and linking parameters.
#
# Some notes.
#
# . `cmake' will overwrite FreeType's original (top-level) `Makefile' file.
#
# . You can use `cmake' directly on a freshly cloned FreeType git
#   repository.
#
# . `CMakeLists.txt'  is provided as-is since it is not used by the
#   developer team.
