I searched for glib.h and have found some. So I wanted to check for  
includes... Nice maze ! All is scattered between many makefiles.
The previous output is make verbose=t liblangtag from repo root. It does  
not display the compile commands that are executed. I hoped it would.

Could someone either:
- fix the issue
- explain me how to display the commandline (so I can get all arguments)  
when $CC or $CXX is invoked
- drive me on another way to fix the issue.

Thank you

Regards
