ftgl : pkg-info misses freetype2

[avilleret]

pkg-config --cflags ftgl returns:

-I/usr/local/Cellar/ftgl/2.1.3-rc5/include -I/usr/local/Cellar/ftgl/2.1.3-rc5/include/FTGL

but FTGL depends on freetype2 header (at least on ft2build.h included in FTGL/ftgl.h)

so FTGL CFLAGS should include freetype2 CFLAGS like pkg-config --cflags freetype2 returns :

-I/usr/local/Cellar/freetype/2.5.3_1/include/freetype2

note that on my Ubuntu system, pkg-config --cflags ftgl returns:

-I/usr/include/FTGL -I/usr/include/freetype2

The freetype information is removed from the pc file by the formula

Since there is no explanation for this I'll probably delete it.

thanks for the quick fix !
