QLibrary::isLibrary seems to miss many libraries.

// path = Install/Debug/plugins/gammaray/gammaray_widgetinspector_ui_plugin-qt5.6-x86_64_debug.so 
qDebug()
        << QLibrary::isLibrary("test.so") // TRUE
        << QLibrary::isLibrary("test.so.45") // TRUE
        << QLibrary::isLibrary("test-qt5.6_debug.so") // FALSE
        << QLibrary::isLibrary("libpython2.7.so.1.0") // FALSE
        << QLibrary::isLibrary("libgammaray_actioninspector_plugin-qt5.6-x86_64_debug.so") // FALSE
        << QLibrary::isLibrary("libgammaray_probe-qt5.6-x86_64_debug.dylib") // TRUE
        << QLibrary::isLibrary("libgammaray_probe-qt5.6-x86_64.dylib") // TRUE
        << "--"
        << QLibrary::isLibrary(QString(path).replace("5.6", "56")) // TRUE
        << QLibrary::isLibrary(path) // FALSE
