CMake: reverting to the previous behaviour for optional prerequisites.

If not found, we trigger the failure of the configuration. This is handled
by macros SALOME_PACKAGE_REPORT_AND_CHECK
and SALOME_LOG_OPTIONAL_PACKAGE, allowing a nice error message which indicates
what flag should be switched off to avoid the issue.
