Hey, I can answer that! :-) (I'm just learning myself...)

I actually had to do this for my own project. You can use:

SET_SOURCE_FILES_PROPERTIES(<file> PROPERTIES COMPILE_FLAGS <flags>)

...replacing <file> and <flags>, of course. Be sure to put <flags> in 
quotes if there are spaces.

Hmm... I *think* '-I' works on MSVC, so you could just use the flags 
'-I<path>'. Or investigate if there is a corresponding property (I don't 
know if there is or is not).

I think SET_TARGET_PROPERTIES is what you want, but I haven't used it.
