[CMake] CTEST_CUSTOM_TESTS_IGNORE regex?

[Leif Walsh]

This variable seems to be interpreted as a normal cmake ;-delimited list. I currently use it that way for other tests. I haven't tried building it as a regex but I kind of doubt that would work, since I know it works as a list. 

If I have to I can duplicate the loops in CTestCustom.cmake but that has other issues (code duplication, size of output when running with -V, maybe speed).
