When trying to build my own app with Qt Quick controls 2 I get this in cmake log: /usr/lib64/libQt5QuickTemplates2.so.5:(*IND*+0x0): multiple definition of `__bss_start' I have this in my cmake: find_package(Qt5 COMPONENTS Core Quick QuickControls2 REQUIRED) add_executable(${PROJECT_NAME} "main.cpp" "qml.qrc") target_link_libraries(${PROJECT_NAME} Qt5::Core Qt5::Quick Qt5::QuickControls2) How to reproduce: Try to build any QuickControls2 example with system Qt: https://doc.qt.io/qt-5/qtquickcontrols2-wearable-example.html One more thing: I found this bug and patch on bugreports.qt.io https://bugreports.qt.io/browse/QTBUG-63083 It may be useful. Using Qtcreator with included libs resolving the problem. But it`s wrong way.
