The imagine package uses some third party libraries under their own license terms:

 * bytemuck 1.0.1 under the terms of Zlib:

error: bytemuck has no candidate texts for license Zlib in ~\.cargo\registry\src\github.com-1ecc6299db9ec823\bytemuck-1.0.1

bytemuck does include the license in LICENSE-ZLIB.md

you should really check alternate extensions like .txt and .md

cargo-lichking/src/discovery.rs

Lines 101 to 104 in 0d29ba6

	name.to_uppercase() == "LICENSE"
	|| name.to_uppercase() == "LICENCE"
	|| name.to_uppercase() == "LICENSE.MD"
	|| name.to_uppercase() == "LICENSE.TXT"

but the license specific ones don't
