Fix “glibconfig.h: No such file or directory” error

I installed glib-devel on Void Linux, and wrote a simple program for test. But the compilation reported following error:

# gcc -I/usr/include/glib-2.0 main.c -lglib-2.0
......
/usr/include/glib-2.0/glib/gtypes.h:32:10: fatal error: glibconfig.h: No such file or directory
   32 | #include <glibconfig.h>
      |          ^~~~~~~~~~~~~~
compilation terminated.

glibconfig.h is in /usr/lib/glib-2.0/include directory, so it should be added into header file search path:

# gcc -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include main.c -lglib-2.0
