compilation error: libgtk3 not found error even though gtk is installed

[shomeAvataar]

While building xatlas, I am getting the gtk not found error even though I have libgtk-3-dev installed. My gtk.h is at /usr/include/gtk-3.0/gtk/gtk.h. I think it is an issue with the premake script.

OS: ubuntu 20.04

premake.lua line 424 needs to be modified to buildoptions(os.outputof("pkg-config --cflags --libs gtk+-3.0"))
