The easiest option with visual studio is to use the /mp compiler flag by setting it in the CFLAGS and CXXFLAGS environment variables in your ctest script. This will parallelize each target across all CPUs. Target-level parallelism may or may not also happen since that's dependent on your local configuration and VS version; Older versions used devenv.exe to drive the build, in which case it's target-level parallelism is only configurable through the IDE, where as newer VS versions can be driven with MSBuild directly and use the /maxcpucount:N switch in the CTEST_BUILD_FLAGS.
Unfortunately on Windows and VS builds there's not really a simple answer. - Chuck On Fri, Sep 5, 2014 at 11:09 AM, Michael Jackson < mike.jack...@bluequartz.net> wrote: > What generator?
