I have a project that depends on numerous 3rd party libraries. Each library is shipped with a license file. These I automatically copy to the deployment folder, where the compiled files are (my own executable and all dependencies).
My question is related to the dependencies of those dependencies. In my mind I should not include those (since we can get into a situation "X of a Y of a Z ...", not to mention cyclic dependencies "X of a Y of a Z of a X") but just to be sure: do I have to copy/mention dependencies of 3rd party software that I do not directly use in my own?
I believe
. Since the product I'm working on is closed-source (but to my knowledge all the direct 3rd party dependencies are MIT, BSD 3 clause etc. licenses, so no GPL or similar) I need to know exactly what the legal aspect is.
