#12387 — python3-openvdb: build against the default python3 version

Hi all,

Could anyone point me at a Debian package (possibly using dh) where
multiple compilation are done (one against python3.7 and one against
python3.8). I'd like to avoid re-inventing the wheel for building a
cmake package (c++) which ships a single python module (so I need to
do one configure+build+install per python version).

Thanks,

Pybuild has a cmake plugin that I think is relatively new.  It may handle the 
complexity for you, but I've never tried it.  We used to do this with pykde4, 
which is available on snapshot..d.o.
