CodeLite IDE

In my building, it sees pkg-config can't find gtkmm-3.0 in pkg-config path.but I truely set in enviroment varieable ,look at my screenshots.
help thank you

I am not sure if it's a true CodeLite issue or GTKMM package missing.
Can you try do this from the command line? does it work? can you upgrade your CodeLite?

I set it in window7 enviroment virable.It's OK,BUT WINDOW DOESN'T COMT OUT,What should I do?
