* use a macro to add resource files for executables and shared libraries
* use that macro to declare targets
* use that macro to set library/binary versioning
* use that macro to set target output name
* use a macro to create manpages and names
If a target is linked against libraries with cmake
(target_link_libraries) and the libraries are not marked as PRIVATE
they are "exported" and in case a other target is linked against this
target it is also linked against *all* (not private) libraries.
Without declaring private libraries PRIVATE a lot of over linking
(linking against unneeded libraries) was done.
