[CMake] Install Prefix and RPM

[Helio Chissini de Castro]

Hi everyone

Is there an easy way to make a different install prefix durong the install 
phase, most directed for RPM construction ( like the old DESTDIR on 
auto*tools ) ?
I have a code that during build parse and substitute de real install prefix, 
and if i set CMAKE_INSTALL_PREFIX pointing to rpm buildroot, i will need to 
do some sed on resulting config files.
