Details from Slack:

> I am specifically trying to re-precompile [CUDA with changed environment variables](https://juliagpu.gitlab.io/CUDA.jl/usage/memory/#Environment-variables). `pkg> precompile` seems to do nothing in my case: I believe it only precompiles packages that obviously need recompiling (after adding or update). The only thing that seems to work is removing the ` ~/.julia/compiled/v1.6/CUDA` directory.
