CMake coudn't find a package configuration file provided by "QT"

[Teg Miles]

I transfered my project from OS Manjaro to Windows 11.
On Manjaro everything works fine but on Windows appears an error connected with CMake:

Could not find a package configuration file provided by "QT" with any of
the following names:

Qt6Config.cmake
qt6-config.cmake
Qt5Config.cmake
qt5-config.cmake

Add the installation prefix of "QT" to CMAKE_PREFIX_PATH or set "QT_DIR" to
a directory containing one of the above files. If "QT" provides a separate
development package or SDK, be sure it has been installed.

How to fix it properly without binding it to specific path on my PC?
Why is this CMake configuration doesn't work at Windows?

The CMake file:

@Teg-Miles said in CMake coudn't find a package configuration file provided by "QT":

find_package(QT NAMES Qt6 Qt5 REQUIRED COMPONENTS Widgets)

I think it should work if you remove this line (on Windows).
The capital T is probably what's causing this error.
Since this line works?!

find_package(Qt${QT_VERSION_MAJOR}
REQUIRED COMPONENTS Widgets LinguistTools WebEngineWidgets TextToSpeech)

@Pl45m4 It works only partially causing another errors to appears and forcing to rewrite rest of the CMake.

I rewrote the CMakeLists:

cmake_minimum_required(VERSION 3.5)

project(Movar_cpp VERSION 1.0.2 LANGUAGES CXX)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

find_package(Qt6 REQUIRED COMPONENTS Widgets
    LinguistTools WebEngineWidgets TextToSpeech)
qt_standard_project_setup()

qt_add_resources(images
    PREFIX "/icons"
    FILES movar.png
)

qt_add_translations(Movar_cpp
    TS_FILES
    i18n/Movar_cpp_uk_UA.ts
    i18n/Movar_cpp_en_US.ts
    i18n/Movar_cpp_ja_JP.ts
    )

qt_add_executable(Movar_cpp
    mainwindow.ui
    mainwindow.h
    mainwindow.cpp
    main.cpp
    dictionarysettings.h
    dictionarysettings.cpp
    dictionarysettings.ui
    fileloader.h
    fileloader.cpp
    app_resources.qrc
    adaptedcompleter.h
    adaptedcompleter.cpp
    adaptedstringlistmodel.h
    adaptedstringlistmodel.cpp
)

target_link_libraries(Movar_cpp PRIVATE
    Qt6::Widgets
    Qt6::WebEngineWidgets
    Qt6::TextToSpeech)

set_target_properties(Movar_cpp PROPERTIES
    WIN32_EXECUTABLE ON
)


install(TARGETS Movar_cpp
    BUNDLE  DESTINATION .
    RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR}
)

qt_generate_deploy_app_script(
    TARGET Movar_cpp
    OUTPUT_SCRIPT deploy_script
    NO_UNSUPPORTED_PLATFORM_ERROR
)
install(SCRIPT ${deploy_script})

I found out that the problem is in qt_add_translation. It doesn't see location of my translation files. And it tries to create it's own folder. I don't know what to do with that.

Also it doesn't download logo icon to left upper corner of the main window.

 QApplication::setWindowIcon(QIcon(":images/icons/movar.png"));

This looks like the new windows 11 style added in Qt6.7. If you don't like it use the old windowsvista style.

I think you've mistaken the topic :D
Your reply probably belongs here

@Pl45m4 somehow yes.... 🙂
