Whenever a binary is created and linked against a static lib that was compiled with LTCG, the final linking step requires the compiler flags so that the pre-compiled data in the shared library can get properly compiled. This could happen for a static build of Qt with LTCG, but also happens frequently for Qt's own build when linking regular libraries and applications against QtBootstrap or QtPlatformSupport. The linking fails when the target is a shared library (example: QtWaylandClient linking against QtPlatformSupport). The .prl file actually contains the "ltcg" flag, so the best solution would actually be to process that flag there and add link_ltcg if any dependent .prl has "ltcg", but I couldn't find out how to do that.
