I need to install MKL manually before it becomes a dependency.

Hellos,

I have my codes on github and I was expecting to run the following command without issues

import Pkg
Pkg.add(url="https://github.com/NoelAraujo/CoupledDipoles.jl")

I noticed that MKL.jl is the source of some problems, because somehow, it cannot be compiled (thus, my runtests fails on github actions)

Sometimes, the error is like this:

(...)
Building MKL → `/scratch/job.617411/input//.julia/scratchspaces/44cfe95a-1eb2-52ea-b672-e2afdf69b78f/e01175ff53c062c52b6cbe441a4382e132f7c82e/build.log`
ERROR: LoadError: Error building `MKL`:

However, here is the important part: when I install MKL first, there is no error to install my codes

import Pkg
Pkg.add("MKL")
Pkg.add(url="https://github.com/NoelAraujo/CoupledDipoles.jl")

My best guess is that there is some racing condition with Julia multi-threading while compiling MKL.

Does anyone had a similar experience before?

@KristofferC Any thoughts?

[prbzrg]

not having the latest version of MKL_jll as compat makes pkg downgrade MKL to a version without compat boundary (that is v0.3)

CompatHelper add it as updated in #142
