This Cmake is a real piece of shit....
Cmake is stripping the path from the ignore black list (ignores.txt
below provided through CFLAGS/CXXFLAGS), which is breaking the
configure. The Blacklist is in PWD, and its on path.
I've tried putting the blacklist (ignores.txt) in CMakeTmp, but it
keeps getting blown away.
How in the hell does one get rid of this Cmake crap???
