Does not build on windows

[CesMak]

Hey there,

I first build rosparam_shortcuts on Melodic Win10, next I tried to:

catkin_make --only-pkg-with-deps moveit_grasps

This fails with:

[ 12%] Built target rosparam_shortcuts
[ 18%] Built target rosparam_shortcuts_example
[ 21%] Building CXX object moveit_grasps/CMakeFiles/moveit_grasps.dir/src/grasp_candidate.cpp.obj
cl : Befehlszeile error D8004 : "/W" erfordert ein Argument.

In another forum it is said that this error means I have wrong compiler adjustements....

I do not know how to get further....
