try_compile: Test that CMake re-runs on input change With the Makefile and Ninja generators we expect that touching the input source file for a try_compile will cause CMake to re-run on the next build. Extend the RunCMake.try_compile test with a case covering this. Also check that CMake does not re-run if nothing has changed. 2015-01-23 14:45:00 +00:00			`message("Running CMake on RerunCMake") # write to stderr if cmake reruns`
