You need to make the distinction between the different styles of build:

 1) Command line makefile
 2) IDE invoked internal build
 3) IDE invoked external makefile

VC supports all three of these usage patterns for its native compiler.
However, if you want to use a cross-compiler then only options 1 and 3
are available.

We use a combination of 1 and 3. We are now using Eclipse as our IDE and
have this setup to invoke external makefiles, and Eclipse can read and
parse the output from this build, so you can use the error navigation
support to jumps to problems.

VC does support parsing of externally invoked tools, but you have to fit
in with how it expects the error messages to be formatted, this is how
we used to integrate Lint into our VC IDE.
