Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipes/gtsam) and found it was in an excellent condition.

[Tobias-Fischer]

Opened a new PR as I didn't have write access in the other PRs. This PR fixes some missing run deps on boost-cpp and adds required tests.

Cool!

[Tobias-Fischer]

I am not sure what's going on with boost on Windows @wolfv - I'm suggesting to skip Windows for now and open an issue in the feedstock, unless you want to play around with the Win build?

[Tobias-Fischer]

It's ready to go :)

[Tobias-Fischer]

I'm giving up on osx, no idea why it still finds the wrong python .. skip as well? Maybe it'll magically work in the feedstock?

[wolfv]

in the last build cmake reports python 3.8 as found?

-- Python toolbox flags                                      
--  Build Python module with pybind                  : Enabled
--  Python version                                   : 3.8
-- ===============================================================

[Tobias-Fischer]

Ah thank goodness. I thought I still saw the system python somewhere. This is ready for merge :)

[wolfv]

awesome!
