I'm not able to compile the ttf part of allegro. I get the following error form cmake
Performing Test TTF_COMPILES - Failed
and it disables the ttf part of allegro. How do I get this to work? I followed Edgar Reynolds guide to compiling allegro 5 on MinGW.

This is my full cmake configure

I also don't understand why it's not detecting GDI Plus
