There is a ruby script kdelibs/cmake/generate_findpackage_file, which asks you 
some questions and then generates a basic FindFoo.cmake file which should 
work for many cases already.

If FreeType is used in several subdirectories, it is ok to add the check to 
the toplevel CMakeLists.txt,
if it's optional:
macro_optional_find_package(FreeType2)
or if it's required:
find_package(FreeType2 REQUIRED)

After that you can use FREETYPE2_INCLUDE_DIR and FREETYPE2_LIBRARIES whereever 
you need them.
