Re-enabled installation of tnl-cuda-arch

The link provided in the comment is not related - tnl-cuda-arch is not
built as a static binary.

Anyway, I don't see any problem with this. Either fix it properly or at
least file a full bug report on Gitlab. Upgrading cmake on your system
might also help...
