[cfe-dev] Adding a framework to a CompilerInvocation

[Félix Cloutier via cfe-dev]

Hi Alex,

To be clear, I’m looking for the equivalent to the -framework parameter. -F is the search path for -framework.

Porting the code over to build an invocation through command-line arguments would be a possibility, then. I’d still like to know if there’s another way, as I’m under the impression that this other way should be simpler.
