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.
Instead of random locations only occasionally related to the
corresponding source.
Includes renaming libgnucash/engine/test/test-extras.scm and
gnucash/report/report-system/test/test-extras.scm to avoid a
naming conflict.
I.e., remove the shell invocation and with it the need to set the shebang.
Surprisingly this required some build-system modifications particularly
for cmake in order to correctly set the environment.
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.
