[CMake] ADD_CUSTOM_COMMAND doesn't create CMake rules

[Schick, Thorben (ITUC; ADITG/DFG)]

And thats exactls the problem...i can't add them via ADD_EXECUTABLE because they don't exist while running CMake...they should be created when the build process is started out of Visual Studio...

Regards
Thorben

You must use the generated files of a ADD_CUSTOM_COMMAND as a dependency.

e.g.:

add_executable( myexe ${_ui} foo.C bar.C )

or:

add_custom_target( myexe DEPENDS ${_ui} )
