Resource files not in explorer

When adding resource files using qt5_add_binary_resources instead of adding them to add_executable, the qrc file is only listed as a simple file under CMake-Modules, and therefore does no longer list the files it contains.

I noticed this when I wanted to put QML-files into an external rcc file. Since the content is no longer listed in the explorer, you can't properly work on them anymore.

I temporarily solved the problem by adding them to add_Executable using a variable I simply comment out.
