Merge branch 'custom-command-generator-expressions' into resolve/tests-if-CYGWIN

The tests-if-CYGWIN topic made a change to Tests/Testing/CMakeLists.txt
in code that the custom-command-generator-expressions topic moved to the
Tests/PerConfig/CMakeLists.txt file.  Make the same change to the same
content in the new file.  (Only a small part of the file moved so rename
detection did not do this automatically.)
