Danger-swift requers libDanger to be in system directories

[msnazarow]

Describe the bug
when danger-swift is installed via Makefile(also via brew, cause brew runs make install PREFIX=/opt/homebrew/Cellar/danger-swift/3.20.2) it copies libDanger into prefix directories(or system if prefix isn't used)
And when it is installed via mise, it copies only danger-swift, and it's not enough

To Reproduce

mise settings experimental=true
mise install danger-swift
git clone https://github.com/msnazarow/DangerMiseCheck
cd DangerMiseCheck
danger-swift local 

Expected behavior

Danger: ⅹ Failing the build, there is 1 fail.
## Failures
Test

Actual behavior

ERROR: Could not find a libDanger to link against at any of: [".build/debug", ".build/x86_64-unknown-linux/debug", ".build/release", "/usr/local/lib/danger", "/opt/homebrew/lib/danger"]

Steps to reproduce:

❯ git clone https://github.com/msnazarow/DangerMiseCheck
❯ cd DangerMiseCheck
❯ git checkout master
❯ git checkout danger-check
❯ mise use danger-swift npm:danger
❯ danger-swift local

I think it's unlikely that mise will copy anything into system prefix directories for you. But the fact its looking in .build/release is a good sign. I wonder if we can copy that into the install directory. I'm not sure what that path is relative to.

The spm backend is still experimental so this sort of problem is expected.

Also @msnazarow your screenshot upload failed, you might want to try again.

As i did here you can path PREFIX to Makefile like
make install PREFIX="${HOME}/.local/share/mise/installs/danger-swift/"

I added ~/.local/share/mise/installs/danger-swift/(version)/lib this path for search in danger-swift

So first of all, there should be libs somewhere, and that directory should be hardcoded in danger sources

[msnazarow]

Screenshot contained lib directory with libDanger and other support swiftmodule files

I see @msnazarow has added the lib path NSHomeDirectory() + "/.local/share/mise/installs/danger-swift/\(version)/lib/danger" but I don't see that lib path in the installs directory, even after #3441 has been merged. Is there a step missing somewhere?

[msnazarow]

@jdx mise run swift build --configuration release --product danger-swift, but it builds only danger-swift, not libDanger.dylib

As i mensioned before, you should reference Makefile and install script

[jdx]

that would only be a solution for this one tool, the backend should support any spm package

[msnazarow]

I think you can just call swift build without --product specification
