Comment (by michaelld@…):

 Welcome to the world of CMake! With a bunch of options, it's often not
 easy to know exactly what to do for some specific issue, nor, when a
 method is selected, if it will work correctly. Most of the time CMake does
 the right thing and also works. But when it doesn't it's often a mystery
 what failed and why. Good for you tracking this one down!

 Maybe these variables should be made optional but on & set like they are
 by default, sort of like the cmake.out_of_source option? That wouldn't
 change current functionality, and would be a cleaner solution than what
 you implemented. And, I'm quite sure some other ports would benefit from
 not setting these variables (either at all, or in the manner that works
 for most ports).
