Installing a package outside current resolver

I'm using stack lts-9.0 snapshot, which includes process-1.4.X. Due to some problems with this version, I would like to use process-1.6.1.0. Adding this version to extra-deps does not seem to be enough:

extra-deps:
- process-1.6.1.0

since this will cause the following error:

Error: While constructing the build plan, the following exceptions were encountered:

In the dependencies for Cabal-1.24.2.0:
    process-1.6.1.0 must match >=1.1.0.1 && <1.5 (latest applicable is 1.4.3.0)

What do I need to do in these cases?

As written in the message, the problem is with Cabal-1.24.2.0 depending on process < 1.5. Add Cabal-2.0.0.2 to the extra-deps.
