Building outside the source directory is not supported.

No more directories under /usr are wanted.  Put the Version specific 
stuff into /usr/lib/singluar/3.0.0 (library), /usr/doc/singular/3.0.0 
(docu) and/or /usr/share/singular/3.0.0 (runtime).

Another option would be to move to /opt/singular/...

Then the package name must reflect the different versions:
singular3-3.0.0
singular2-2.x.x
singular1-1.x

This should be named more unique.

This is ok IMO.
