[Mingw-cross-env-list] Using fontconfig with mingw-cross-env

[David Bruce]

Hi Volker et al,

Having got tuxmath + t4k_common to build nicely with mingw-cross-env,
I'm now trying to deal with run-time issues.  Namely, since we use
fontconfig (via SDL_Pango), we need to get fontconfig's config files
installed onto the target system.  Some of the libraries in
mingw-cross-env install files into
/opt/mingw-cross-env/usr/i686-cp-mingw32/share and */etc. Apart from
fontconfig's config files, other examples in mingw-cross-env are the
graphics files for the gtk and qt widgets.

Is there a standardized/recommended way to get these non-code files
onto the user's Windows box when building with mingw-cross-env?  I can
hard-code something into tuxmath's NSIS script, but I hate to reinvent
the wheel if there is a "right" way to do this already.

Thanks for any help,

David Bruce
