document libedit as build dependency (by llvm) or remove it or/and how it can be disabled (with consequences)

[matu3ba]

See in LLVM repo ./cmake/Modules/FindLibEdit.cmake for why its a build dependency.

Can be disabled with -DLLVM_ENABLE_LIBEDIT=off, but I am unsure if there are bad implications for the intended use cases.

it should be disabled

Solution:

• 15.0.0: cmake is failing because cannot find GNUInstallPackageDir, ExtendPath and FindPrefixFromConfig llvm/llvm-project#57573 (comment)

@LinuxUserGD True, but its not disabled on the first LLVM build.
