I am installing muPDF.
I gave an input like make prefix=/usr/local install
in terminal
I have installed XQuartz already
But I get an error as follows
In file included from thirdparty/glfw/src/context.c:28:
In file included from thirdparty/glfw/src/internal.h:85:
thirdparty/glfw/src/x11_platform.h:35:10: fatal error: 'X11/Xlib.h' file not found
