[CMake] CMake make test feature?

[Belcourt, Kenneth]

Hi,

This is probably old news but is there some reason why I can build my  
code in parallel with make -j8, for example, but trying to run the  
tests in parallel with make -j8 tests ignores the -j option.  I've  
resorted to invoking ctest with -j8 which works fine.  Any way to  
normalize the behavior so that builds and tests behave the same with  
respect to the -j option?
