Fix for issue #5041 - improve error messages that may occur during ctest_build and ctest_configure.

The improved text gives very clear information when either the CMakeLists.txt or CTestConfig.cmake file is missing. Hopefully, it makes it easier for those poor future souls who encounter these messages to solve their problems quickly.
