@dalcinl is right, same error in the smcuda btl makefile.am. does this conda-forge build using --enable-static and/or --enable-mca-dso? Just asking because i'm curious why spack build with cuda support didn't hit this but did hit the problem in the accelerator cuda component.

i'll open a PR on main first with this fix.

[dalcinl]

@hppritcha conda-forge is using --enable-mca-dso. I would have liked to just enable DSOs for CUDA and UCX, but I could not manage to find the right list of components to make these libraries optional 😞, so I gave up and passed --enable-mca-dso for everything.

@hppritcha let's wait to merge this until we get cherry-pick of this #12083 as well

@janjust pushed the additional commit to this PR. So 5.0.x will get two for the price of one!
