Any scm file that will be built may need access to other scheme files that may have
been linked into that directory. As it was only scm files that would be linked
themselves would also be built with the search path set, causing other linked files
not to be found for an scm file that doesn't add a link for itself.
This version is available for all supported platforms and distros
(CentOS can have a version via EPEL, which is required anyway)
Advantages:
- one cmake version for all platforms
- we can drop all conditions based on cmake version
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.
