ft2build.h not found

Despite CMake succesfully completing and finding Freetype, I'm getting the following error:

[ 0%] Building CXX object MyGUIEngine/CMakeFiles/MyGUIEngine.dir/src/MyGUI_ResourceTrueTypeFont.cpp.o
/Users/calderco/Developer/MyGUI/MyGUIEngine/src/MyGUI_ResourceTrueTypeFont.cpp:29:23: error: ft2build.h: No such file or directory

make[1]: *** [MyGUIEngine/CMakeFiles/MyGUIEngine.dir/all] Error 2

Any help would be greatly appreciated.

EDIT: Fixed by copying "/usr/X11/include/ft2build.h" to "/usr/X11/include/freetype2/ft2build.h"
