I'm no CLion expert, but I don't know that it supports gnu make yet. So you'd be able to code in the app, but not build from CLion. Local development and building of firmware uses gnu make IIRC.
CLion looks like it supports gdb, so you might be able to get debugging working.
Maybe someone has gotten the whole ball of wax working. If so, that'd be cool. I like Jetbrains' stuff and would totally use CLion if it'd work.
