Do not run cpack at CMake time it is not available.
cpack was used to get the list of available i.e. ACTIVE CPack generators in the CMake tests suite. This was done in order to get dynamically available CPack generators like DEB or RPM that may or may not be available on some platform like MacOSX depending on the fact that some command are installed or not. We may do that but not during initial configuration. The current patch fixes the problem and we may do better in the future like configuring CPack tests later.
