Not all modules are enabled after build

[harajyoti_das]

I enabled the /MP flag in CMake and set the num_processors to 1.
default the flag is unchecked and num of processors for my machine was 8(= no of cores)

I set the number of parallel projects build to 1 (default is 8 for my machine as I have 8 core) This is under Tools-> option

For reference, @lassoan committed a fix that creates the missing directory just before using it, so parallel build should work now as well.

Build error on Windows related to CLI build directory

Submitted a fix for this build error: https://github.com/Slicer/Slicer/commit/f59653b8b7aa527ceeaacfa3296b009064619bf7 It would be still nice to find out why CMake behavior is changed but right now I cannot spend more time with this investigation.
