Cmake (Clion) cant link QT5 UiTools

[Marc Haubenstock]

I have a cmake file for various dummy Qt5 applications.

cmake_minimum_required(VERSION 3.15)
project(Qt_demo)

set(CMAKE_CXX_STANDARD 17)

# Tell cmake where Qt is located
set(Qt5_DIR "~/Code/Cpp/Qt/5.12.6/gcc_64/lib/cmake/Qt5")

#enable mocking compiler
set(CMAKE_AUTOMOC ON)

#enable ui compiler
set(CMAKE_AUTOUIC ON)

#enable resources
set(CMAKE_AUTORCC ON)


# Tell cmake to find the modules Qt5Core and Qt5widgets
find_package(Qt5 COMPONENTS Core Widgets UiTools REQUIRED)

get_target_property(QtUiTools_location Qt5::UiTools LOCATION)

message("${QtUiTools_location}")


add_executable(screenshot_demo screenshot/screenshot_main.cpp screenshot/screenshot.cpp)
# Link the library to the executable
target_link_libraries(screenshot_demo Qt5::Core Qt5::Widgets)

qt5_add_resources(RC_SRC "application/application.qrc")
add_executable(application_demo application/main.cpp application/mainwindow.cpp ${RC_SRC})
qt5_use_modules(application_demo Core Widgets)

qt5_add_resources(CALC_RC_SRC "calculator_builder/calculatorbuilder.qrc")
add_executable(calculator_builder_demo calculator_builder/main.cpp calculator_builder/calculatorbuilder.cpp ${CALC_RC_SRC})
target_link_libraries(calculator_builder_demo Qt5::UiTools Qt5::Core Qt5::Widgets )

Furthermore I added the Qt5 desinger as an external tool in clion as per setup

The first two projects compile and run just fine. However in the last project (calculator builder) I am trying to use UITools which is a Qt5 Addon. When I hit the compile button I get the following error:

I am totally lost. Any help would be greatly appreciated

Since it's a static library you may try to move it after the libs which provide those functions.

[Marc Haubenstock]

it seems a magical deletion of the cmake-build-debug folder and rerunning of the cmake file has fixed this

What would the cmake file look like? I am not a big cmake pro

move the QtCore and QtWidget lib before the QtUiTools lib in the cmake command.
