GTK header files not found at build

[symdeb]

Wonder if this design would be useful for a home EMC lab testing for DYI PCB ? If understanding it, well, up to 2GHZ would be required and wth this tool it can support 3GHZ. it would fit the requirements?

P.S: please advise the GTK libraries to install. Tried libgtk-3-dev build getting severa missing header files errors

Also modified the Makefile as: GTKINC = $(shell pkg-config --cflags gtk+-3.0) GTKLIBS = $(shell pkg-config --libs gtk+-3.0)
