I’m having trouble with Cmake and the produced ninja “make-files”  
All seems to go well with “Cmake -GNinja”, but the commands to  
produce a .res file is wrong. It includes a “/MP” E.g. if I do a  
‘ninja.exe gnuradio-runtime’, which gives:

[1/2] Building RC object  
gnuradio-runtime/lib/CMakeFiles/gnuradio-runtime.dir/gnuradio-runtime.rc.res  
FAILED: “G:/MingW32/bin/CMake/bin/cmcldeps.exe” RC … /MP /bigobj  
…  
/fognuradio-runtime/lib/CMakeFiles/gnuradio-runtime.dir/gnuradio-runtime.rc.res  
…

fatal error RC1106: invalid option: /MP  
ninja: build stopped: subcommand failed.

Not sure if this is the fault of Cmake, Ninja or GnuRadio.
