(Background is issue #18622)
CMake errors out when the Kuka files are removed with:
```
CMake Error at cMake/FreeCadMacros.cmake:79 (ADD_CUSTOM_COMMAND):
ADD_CUSTOM_COMMAND called with wrong number of arguments.
Call Stack (most recent call first):
src/Mod/Robot/CMakeLists.txt:47 (fc_target_copy_resource)
```
The problem is that while the CMake code checks whether /src/Mod/Robot/Lib/Kuka is there befor setting Robot_Resources, but then later still uses the variable, even if it hasn't been set.
The patch just guards the failing fc_target_copy_resource with another if that checks whether the variable has been defined.
CMake install would also fail when Lib is empty, so another guard is required for the `INSTALL( DIRECTORY Lib` … section.
(found while searching for the build error on armhf/armel on Debian
buildds, once resolved will make an additional PR for that.)

In older versions it was possible to copy elements with drag and drop by holding the CTRL key. Since v0.20 or v0.21 this wasn't possible any
more so that elements are always moved.
Note: Copying is only allowed for elements that have a parent object.
