font_tool work (well, it does not work because there are some compilation error due to system specific libs I think, but I have it working if I change some code in src/font_tool/main.cpp, but I don't want to commit my modifications since I am not sure what this tool should do).

Remove the DEBUG option, since cmake has already one to do that, -DCMAKE_BUILD_TYPE=Debug
