[Cmake] install on Unix - paths

[William A. Hoffman]

The only thing you can do is set CMAKE_SKIP_RPATH in the cache.
I don't think that autotools patches the libraries, it just does
not set the rpath.  I do not think it is possible to patch the libraries
after they are created.  The idea is, if you are building for an install,
the libraries will be installed into a path that is in LD_LIBRARY_PATH or
some other system area that is known by the ld.so program and rpaths will
not be needed.
