How to build?

[HuStmpHrrr]

Sorry to ask a stupid question but I just can't build from master branch. I am wonder how am I supposed to build? I am using Coq 8.8.1 and equations, but it keeps fail to build with follow messages:

NOT IN _CoqProject: Instance/LambdaOld.v

The 1st term has type "Type@{Category.Lib.Datatypes.1007}"

Even if I added those missing files to _CoqProject, it still fails to build, not to mention the universe inconsistency. How should I proceed?

Also, it seems Lambda depends on Metalib, which is not stated as dependency in README. Can I just skip Lambda entirely?

Hello! This library has never worked with 8.8.1, due to a bug that I reported which was fixed in 8.8.2. Please let me know if the problem persists after upgrading.
