# As a preliminary, create a compilation directory and change into it, for
# example
#
#   mkdir ~/freetype2.compiled
#   cd ~/freetype2.compiled
#
# Now you can say
#
#   cmake <path-to-freetype2-src-dir>
#
# to create a Makefile that builds a static version of the library.
#
# For a dynamic library, use
#
#   cmake <path-to-freetype2-src-dir> -DBUILD_SHARED_LIBS:BOOL=true
#
# For a framework on OS X, use
#
#   cmake <path-to-freetype2-src-dir> -DBUILD_FRAMEWORK:BOOL=true -G Xcode
#
# instead.
#
# For an iOS static library, use
#
#   cmake <path-to-freetype2-src-dir> -DIOS_PLATFORM=OS -G Xcode
#
# or
#
#   cmake <path-to-freetype2-src-dir> -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 some files in the source tree in case you don't
#   call it from a build directory as described above.
#
# . 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.
