So you'll rewrite depslib :lol:

Pecan:
Something like the following might help you get the dependencies that CB already sets up.

I would need CB to make this work while one of major requirements is to avoid dependency from anything but .cbp/.workspace file.

p.s. Even just linking with CB SDK is not a solution, this would make me stuck with too large 3rd party code base.

It looks to me that depslib does not depend on Code::Blocks.

I meant that example of WX/CB-based code posted by Pecan.

p.s. Actually I'm already somewhere in the middle of implementing dependency management and will release as soon as it is ready.
