It doesn't change anything in between CMake configures, but it does 7 altogether, with the expectation that the output will not change beyond the 1st / 2nd configures. Sample output here: https://open.cdash.org/testDetails.php?test=331119724&build=3788470 The test doesn't presently fail if there are diffs between configures. Although one could argue, maybe it should... You could definitely do something similar for a test that changes a cache value in between runs. HTH, David C.
