Well, I don't know how many variables might be affected by this. Maybe
it's breaking more things that it's supposed to fix. I was just
wondering, because I ran into this problem more than once. Besides, you
do not have to specify the absolute path to the CMakeLists.txt file
you're feeding to cmake (I agree, though, that that's not exactly the
same thing.)
