In a Visual Studio 2005 Add-In, how would one specify that a new set of generated C++ source files should be compiled instead of the original source files? Since the two exist in separate directories, I assume that there's some way to change the source directory from the VCCLCompilerTool interface, but I haven't been able to figure out how yet. I get the feeling from the documentation that this isn't the correct interface for what I'm trying to do. Any ideas on what would be the correct interface?
EDIT: I tried the VCProject and VCConfiguration interfaces also. No luck.
