[GLIBMM] Installing .pc file

[faserg1]

Prepare and install atk.pc file.
Should also fix atkmm #9564

[faserg1]

Updated also libsigc++, but need to install glibmm_generate_extra_defs.

[faserg1]

@JackBoosY I am stuck in compiling atkmm. There is a strange problem, and I don't know how to solve it with native configure&make. Atkmm using other libraries and links them in wrong order, so compiling fail.
Maybe a good variant as in other ports create a CMake file to build it? I just don't sure.

Should link with pcre, pthread and libffi. Add -lpcre -lthread -lffi should fix this issue.

@JackBoosY I found problem and I know solution.
There is a glib-2.0.pc.in file, and there is a line:
Requires.private: @PCRE_REQUIRES@
As documentation of pkg-config sais:

On the other hand, libraries from Requires.private will only be included when static linking.

But that field on glib-2.0 is not configured. But should, as some other libraries.
Atkmm libs are configuring with this command: pkg-config --libs "atk >= 1.18 glibmm-2.4 >= 2.46.2".
