Qt5 icons not showing in Cmake generated executable

I have a Qt5 Project and I'm compiling it with Cmake.

I added a .qr file with the icons.

In QtCreator, I see the icons in Design Mode, but compiling it, it doesn't show them. I tried different changes in Cmake, but I can't find what's wrong. Here is my CMakeLists.txt:

CMAKE_MINIMUM_REQUIRED(VERSION 2.8.11)

PROJECT (UtilityDICOM)

FIND_PACKAGE(Qt5Widgets REQUIRED)

SET(CMAKE_INCLUDE_CURRENT_DIR ON)
SET(CMAKE_AUTOMOC ON)

SET(CMAKE_AUTOUIC ON) # necessary?

SET(UI_FORMS
    View/UI/mainwindow.ui
)

SET(UI_RESOURCES
    View/Resources/iconos.qrc
)

SET(UI_QT_CXX
    mainwindow.cpp
)

SET(UI_MOC_HEADERS
    mainwindow.h
)

QT5_WRAP_CPP(UI_WRAPPED_MOC_HEADERS ${UI_MOC_HEADERS})
QT5_WRAP_UI(UI_FORM_HEADERS ${UI_FORMS})
QT5_ADD_RESOURCES(UI_RESOURCES_RCC ${UI_RESOURCES})


ADD_LIBRARY(ui_qt ${UI_QT_CXX}
    ${UI_WRAPPED_MOC_HEADERS}
    ${UI_FORM_HEADERS} ${UI_RESOURCES_RCC}
)

ADD_EXECUTABLE(UtilityDICOM WIN32 main.cpp)
TARGET_LINK_LIBRARIES(UtilityDICOM
    ui_qt
)
QT5_USE_MODULES(UtilityDICOM Core Gui Widgets)

I also tried adding ${UI_RESOURCES_RCC} in ADD_EXECUTABLE, with same result.

Any ideas? Thank you.

Finally I got it.

In the CMakeLists.txt:

Despite I saw examples where the resources were added inside a TARGET_LINK_LIBRARIES,

I added the resources variable inside the ADD_EXECUTABLE:

ADD_EXECUTABLE(UtilityDICOM WIN32 main.cpp ${UI_RESOURCES_RCC})

after deleting the target folder and generating again, it worked.

Thanks everybody. Maybe this is helpful to other people.

qt uses plugins to handle the image loading.

you application directory should look like

<root>
  -myapplication
  -<imageformats>
    -libq* // the actual image plugin you need (if jpg then 'libqjpeg')

you can find the imageformats under <qt root dir>/plugins/imageformats

cheers
