The problem here is that you ask to install the files/programs to an
absolute path
i.e. "/usr/bin".

Not all CPack generator can transparently handle absolute install path.
Usually one uses relative install path like "bin" package it and then
when you unpack (the RPM, the zip, the STGZ etc...) you chose the
installation prefix.

In your case CPack is trying to install to /usr/bin where you may not have
the right to write.

For more information on CPack and absolute destination handling see:
