No .so nor .cmake files are being installed by running setup.py

When compiling pyside with setup.py the libraries for libpyside and libshiboken are only installed in their .so.6.2.4 form, but the .so, .so.6, .so.6.2 versions are not (they are present in the build system).

They also set rpath, which might be good for creating wheels but not for distro packaging.

Ideally the user should be able to pass a parameter in order to get the headers installed into /usr/include and the libraries into /usr/lib/<whatever> (each whit it's own parameter), and avoid setting rpath.

This might be considered not necessary if the same can be done with CMake, but having the choice would be just great.
