Summary:                    CMake generated solutions don't build projects in
parallel.
Description: 
The project-level parallelism available via the Tools -> Options -> Projects and
Solutions -> Build And Run appears to be non-functional. The output window will
show the solution being build sequentially one project at a time despite no
dependencies between many projects. Task manager shows many MSBuild.exe
processes but only 1 cl.exe going.

This is especially annoying when building projects with hundreds of target like
ITK with tests on. It will literally take 3 hours on a very fast 12-thread
machine whereas the same compile under gcc will be done in under 15 minutes.


Steps to Reproduce: 
Run CMake on ITK source with default settings.

Click on Build -> Batch Build -> Select ALL_BUILD for any configuration you want
(or all of them, it makes no difference) -> Build.

Observe that only 1 project is being build at a time.
