I can't find any such patch for the debian packages via this system:
https://sources.debian.net/patches/gtkmm3.0/
https://sources.debian.net/patches/glibmm2.4/

Please show us the output of these commands, so we can see exactly
where this -std=c++11 is coming from:

$ pkg-config glibmm-2.4 --cflags
$ pkg-config gtkmm-3.0 --cflags

Indeed. It does not, for this very reason.

Yes. Adding it as CFLAG from pkg-config would cause this very problem.
