--ignore-project creates "Invalid package ID" error

[jwaldmann]

git clone https://github.com/tidalcycles/Tidal
cd Tidal
git checkout 1.6.1
cabal install --lib --ignore-project

will result in

cabal: Invalid package ID: .

The repo contains a file cabal.project with contents

packages: ./ tidal-parse

Just running

cabal install --lib

will produce some error triggered by constraints in tidal-parse/tidal-parse.cabal - that I want to avoid by not building it.

I thought that --ignore-project tells cabal to ignore cabal.project. (although -? says "Ignore local project configuration" and does not mention the file name).

• This behaviour changed for cabal >= 3.4, as described in cabal v2-install --ignore-project crashes when project file is present #8094
• --ignore-project is still not fully supported for v2 commands as described in Add --ignore-project to v2-build #7057

So i am gonna close this one in favour of #8094, more recent and including the < 3.4 behaviour
