[Haskell-cafe] Cabal 3.2.0.0, run okay with profiling enabled, but installed exe NO profiling enabled

[Albert Y. C. Lai]

3.4.0.0 does the same. I am not sure whether it is a bug or a feature.

Workaround: Write a cabal.project file that goes like:

packages: .

package *
   profiling: True

https://cabal.readthedocs.io/en/3.4/cabal-project.html has every 
variation and fine-tuning.
