Cabal version mismatch when using a custom Setup.hs

[kokobd]

Currently, cabal-hoogle reads setup-config file produced by Cabal library. That file is not backward compatible.
This can only be solved properly when Cabal supports --enable-build-info, see this upstream issue.
As a workaround, you may add a constraints section to your cabal.project.local, so that your Setup.hs uses the same Cabal as cabal-hoogle, like below:

constraints:
   Cabal == 3.6.2.0 -- change this to the Cabal version you used to build `cabal-hoogle`
