Dear Antoine, It seems related to the question: how far is your project (that would be globally licensed under OSL) a derivative of the GPL-3.0 code, or not? It is also related to your legal framework, in so far the various codes are more or less closely linked. The European legal framework considers that the normal and fair use of a tool (like a library, according to its usage instructions, without modifying the library source code) does not make resulting works "derivatives" of the used tool. In addition, it states (in my opinion) that linking different components, for the sole and fair purpose of making these components interoperable, is a copyright exception and cannot be restricted by the copyright owner. This temperate a lot the theory of "strong copyleft" on this point. (Law lovers will reed Recital 15 of *Directive 2009/24/EC <https://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=CELEX:32009L0024&from=EN>*).
An alternative solution is the use of the EUPL-1.2 that is expressly covered by the European legal framework and is expressly compatible with both the OSL and the GPL-3.0 More on joinup.eu and in particular the recent JLA (joinup licensing assistant) https://joinup.ec.europa.eu/collection/eupl/joinup-licensing-assistant-jla .
