lttngpy fails to build on Windows Debug

[clalancette]

Looking at the nightly builds, it looks like the new lttngpy package fails to build on Windows Debug: https://ci.ros2.org/view/packaging/job/packaging_windows_debug/2070/

In particular, the end of the trace says:

@christophebedard can you take a look?

can you take a look?

Will do. I'm guessing this is something that other packages using pybind11 (and thus Python) have to deal with too, so I'll start there.

Thanks, appreciated.
