Add "run" option to contextual menu of executable artifacts in CMake projects

Just as it happens with standard QMake-based projects, it would be great to have an option in the contextual menu of the Projects panel to run executables. I've migrated a big project with subprojects (that used the SUBDIRS template) to CMake, the subprojects each generate an executable that should be run together because they follow a client-server architecture. 

It's kind of inconvenient having to open the selection panel in the bottom left to choose the executable then click the run button, and the same process again with the rest of the executables. It used to take just one right-click and a left-click, that's it.

I think it should be doable, as currently the tooltip that appears properly identifies the artifact as an EXECUTABLE and prints the path too, so it should be just a matter of launching the process.
