A similar idea was mentioned on IRC a while ago, in that case it was using 
https://github.com/rizsotto/Bear .

The user did manage to get a "CMake" project working from their generated 
compile_commands.json after applying this [1] hacky patch (which I wrote the 
initial version of), and it reportedly worked better than the 'Custom Make' 
plugin without needing hand-entered include paths etc.

+1, this seems like a good idea.
