🎉 works great !

Though the arguments following the greedy arguments don't seem to be detected as I expected:

For example, here I was expecting a symlink install:

colcon build --packages-select console_bridge --cmake-args -DBUILD_TESTING=ON -DFOOBAR=OFF  --symlink-install

Is there some kind of delimimter that should be used ?

For example, here I was expecting a symlink install:

It seemed to work for options following the greedy one in my local testing. Can you double check the logs what args have been parsed.

Is there some kind of delimimter that should be used ?

No delimiter.

Also console_bridge is a plain CMake package, no? I doubt that can do a symlink install in the first place...

Oh yeah that could be it, I took the first non-python package from my topological order ^^ poor choice...

Works fine with class_loader 👍 sorry for the noise

I didn't get a chance to test many configurations but, from the few scenarios I tested, this PR works perfectly 👍
(tested only cmake-args and ctest-args so far)
