glib errors on cygwin

I want to compile and install geany text editor in Windows 7 by using cygwin. I follow the usual way to compile and install C source: ./configure make make install the configure script was successfully running and give me no errors.In the make step i have the following errors : ctags.c:23:18: fatal error: glib.h: No such file or directory #include I have installed pkg-config and also add the pkg-config output to makefile by doing the following: CFLAGS = $(shell pkg-config --cflags glib-2.0) CXXFLAGS = $(shell pkg-config --cflags glib-2.0) LIBS = $(shell pkg-config --libs glib-2.0) This is the output of the pkg-config $pkg-config --cflags --libs glib-2.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -lglib-2.0 -lintl -lpcre -lintl - liconv -lpcre $ pkg-config --libs glib-2.0 -lglib-2.0 -lintl -lpcre -lintl -liconv -lpcre Any idea how to fix this ?
