This reverts commit 1a9fcfefad because
on MinGW cmake complains about the paths in pkgconfig files. This can
be addressed by using the MSYS2 cmake instead of the MINGW32 one, but
that requires some other changes... and there's also a path separator
bug in that version of FindPkgConfig.cmake.
gtk-mac-bundler can't access the executable's rpath list so it can't
follow dependencies if they're not in $install_dir/lib from @rpath.
Autotools always sets absolute path install names so this should have no
adverse affects on other Mac builds.
It is split into
- /libgnucash (for the non-gui bits)
- /gnucash (for the gui)
- /common (misc source files used by both)
- /bindings (currently only holds python bindings)
This is the first step in restructuring the code. It will need much
more fine tuning later on.
