When using the current master of omc to generate an FMU, the file <model>_info.json is put directly into the resources folder inside the FMU. However, FMI4cpp looks for it in the folder "resources" + getOs() + "/" + getLibExt(), which for me is resources/linux64/.so and thus cannot find the file.
Is this a bug? When I remove adding getOs() and getLibExt() everything works as expected.
