Heh, and the code indeed did hit the only breaking change I made there. I hoped it wouldn't.

/home/circleci/project/habitat-sim/src/esp/assets/GenericMeshData.cpp:69:32: error: no match for ‘operator=’

Change this:

habitat-sim/src/esp/assets/GenericMeshData.cpp

Line 69 in 99e5fdc

collisionMeshData_.indices = meshData_->mutableIndices<Mn::UnsignedInt>();

to this, and similarly in other places if those fail the same way:

  collisionMeshData_.indices = meshData_->mutableIndices<Mn::UnsignedInt>().asContiguous(); 

The remaining Magnum changes got just merged, so you can update the submodule to mosra/magnum@5f16354.

Oh also, there's a new Utility::String::parseNumberSequence(), which is now used in TestSuite --only and --except arguments. Useful to quickly run just a subset of test cases (--only 244-260, for example) if you have huge or slow tests (which was the case for the shader stuff).
