FledgePower is an open source project licensed under the Apache License, version 2.0. All contributions to this project are licensed under this license.
Some librairies used for plugins development can be licensed under a license which is not compatible with Apache v2 (ex: GPL v3)
This is shouldn't be a concern for using or contributing to FledgePower as long as the source code of the GPL v3 library is not directly distributed in the plugin's repo but referenced in the documentation so a user can download it and compile it separately on its own machine for private use. In this case, there is no issue and we are fully compliant with the GPL v3 rules.
