Special version format for non-poulp dependencies
Libraries that are not build with poulp doesn't support semantic versionning, and place their versions in their names. So we end up with quoted dependencies everywhere in our manifest.
We could have a special version format, like
x.x in the manifest that will just be appended to the lib name.
[dependencies] libsoup = "2.4" # Not a semver version -> --pkg libsoup-2.4 semver = "0.1.0" # semver version -> --pkg semver
