Whaaat??!  You can't do that, CMake uses absolute paths when it
configures a build.

Doesn't sound done quite right.  Build from a pristine source dir and
do an out-of-source build.

I wonder if this is a cross-compilation problem under your XP emulator.

Could be a MSYS specific problem under your XP emulator.  Or it could
be you got your build directories cleaned up.  Try on MSYS with a
pristine source tree and an out-of-source build.
