Add test of all available CPack generators. Add this test with the goal of increasing coverage of the cpack source code, even/especially when the underlying packager tool is not installed. The test does not fail if there is a cpack problem with a certain generator. I expect some generators will fail on every machine running a CMake dashboard.
