@alienquake you inferred static linking where there is one executable (all dll/files inside). that would be verboten under LGPL.
Static linking is not forbidden under LGPL. If the app uses statically linked LGPL library, all you have to do is provide your object files and the LGPL requirement is still satisfied. Or use Dynamic-Link Library Redirection feature. It's written inside LGPL FAQ: https://www.gnu.org/licenses/gpl-faq.en.html#LGPLStaticVsDynamic
