Would it be ok to include in this PR the removal of trailing whitespace on line 412 of the resulting CMakelist.txt? I keep forgetting to disable trailing whitespace removal in my editor for just this one file which I then have to go manually fix-up during review. So far it seems to be the only file I've edited for this work that has trailing whitespace cruft.
