@jslee02 this PR causes python bindings on my system (Xubuntu 18.04) to fail with segfault everytime I do import dartpy (I will try later today on my archlinux system to check if it makes it break there also). Any ideas what could be causing this? Is it passing the tests (I assume you have tests for executing python examples)?

[jslee02]

Did it work on your system before this PR?

Yes: https://github.com/dartsim/dart/runs/665747409#step:4:583

Did it work on your system before this PR?

Yes and I tried again going back to a previous commit and it is working again.

I am using Ubuntu 18.04, but they still pass in your CIs.

Any ideas on what I can check? I could do a debug build and see if I can find something in the trace but I doubt it.

@jslee02 in arch-linux I am getting the following when doing import dartpy:

ImportError: /usr/lib/python3.8/site-packages/dartpy.cpython-38-x86_64-linux-gnu.so: undefined symbol: _ZN4dart6python15CollisionFilterERN8pybind116moduleE

Again, if I revert to a previous commit, it is working.

@jslee02 after cleaning up the cmake build folder and re-configuring, it seems that it is working. So, I guess it was a CMake thing.. Sorry for the fuzz..

Glad it worked!
