[Vm-dev] Problems with building a freetype plugin on linux

[Andreas Raab]

Just FYI, this include is just plain broken in FT2Plugin. The correct 
usage of Freetype is by using the macros, for example FT_FREETYPE_H and 
FT_OUTLINE_H. The correct macro to use here is:

	cg addHeaderFile: 'FT_TRUETYPE_TABLES_H'.

Instead of using either 'tttables.h' OR 'freetype/tttables.h' See the 
Freetype documentation about using the header files correctly:

http://freetype.sourceforge.net/freetype2/docs/tutorial/step1.html

The reason it works on Windows is that I'm going out of my way to add 
freetype/ to the include path (which is wrong too but it works).

Cheers,
   - Andreas
