[CMake] Parallel build with ctest 2.8.2

[David Cole]

I am guessing that this commit from Dec. 2009:
0b38bb4c535ae972d7f973e3e69945a6d0c14d75

to fix this bug:
http://public.kitware.com/Bug/view.php?id=2336

is related to your problem...

I would recommend updating your script to a "new-style" (since ctest 2.4 at
least) script that uses the ctest_build() (and related) functions rather
than executing "-D Nightly" as a CTEST_COMMAND. But... that's just a way to
make it work with this newer ctest. There should still be some way to pass
-j flags to an old-style script, or for use with a -D command line.

If anybody figures out why this is happening, please reply to this thread
with a recommended fix to the code.

I am not surprised that this bug fix introduced a new issue like this. It
was a tricky one to try to figure out a completely backwards compatible
solution for.


Thanks,
David
