I was trying to reproduce your issue and can confirm, that screengrab does not respect the DCMAKE_INSTALL_PREFIX. Your patch will probably set the correct path for the screengrab binary but not for the libraries, which are installed to /usr/lib/screengrab. This is why screengrab segfaults on start.
