Yes, as alluded to above
the complete result for cmake --trace --debug-output for
a CMakeLists.txt file consisting of just
project(test NONE)
enable_language(CXX)
was attached to my first post in this thread. Part way through is starts
accessing CMakeFortranInformation.cmake which is the source of the trouble.
For your convenience I will attach that cmake output to this post as well.
