[cairo] cairo-ft.h

What `pkg-config --cflags freetype2 cairo` would return in your environment?
In my case, it returns like below.

$ pkg-config --cflags freetype2 cairo
-I/usr/include/cairo -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -I/usr/include/pixman-1 -I/usr/include/uuid -I/usr/include/freetype2 -I/usr/include/libpng16

The code you pasted,

> #include <cairo/cairo-ft.h>
> //#include <cairo.h>
> //#include <cairo-ft.h>
> 
> #include <freetype2/ft2build.h>
> //#include <ft2build.h>

looks like the situation that CFLAGS was not set properly, and cannot find cairo.h or ft2build.h, and you might have tried to fix by a workaround in C source (and failed). Please check your `pkg-config --cflags freetype2 cairo` you wrote in Makefile
