Qt CMake Project can not build

ZeusFa

I opened qt creator and created a cmake project with the following CMakeLists:

cmake_minimum_required(VERSION 3.5)

project(untitled2 VERSION 0.1 LANGUAGES CXX)

set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

find_package(QT NAMES Qt6 Qt5 REQUIRED COMPONENTS Widgets)
find_package(Qt${QT_VERSION_MAJOR} REQUIRED COMPONENTS Widgets)

set(PROJECT_SOURCES
        main.cpp
        mainwindow.cpp
        mainwindow.h
        mainwindow.ui
)

if(${QT_VERSION_MAJOR} GREATER_EQUAL 6)
    qt_add_executable(untitled2
        MANUAL_FINALIZATION
        ${PROJECT_SOURCES}
    )
# Define target properties for Android with Qt 6 as:
#    set_property(TARGET untitled2 APPEND PROPERTY QT_ANDROID_PACKAGE_SOURCE_DIR
#                 ${CMAKE_CURRENT_SOURCE_DIR}/android)
# For more information, see https://doc.qt.io/qt-6/qt-add-executable.html#target-creation
else()
    if(ANDROID)
        add_library(untitled2 SHARED
            ${PROJECT_SOURCES}
        )
# Define properties for Android with Qt 5 after find_package() calls as:
#    set(ANDROID_PACKAGE_SOURCE_DIR "${CMAKE_CURRENT_SOURCE_DIR}/android")
    else()
        add_executable(untitled2
            ${PROJECT_SOURCES}
        )
    endif()
endif()

target_link_libraries(untitled2 PRIVATE Qt${QT_VERSION_MAJOR}::Widgets)

set_target_properties(untitled2 PROPERTIES
    MACOSX_BUNDLE_GUI_IDENTIFIER my.example.com
    MACOSX_BUNDLE_BUNDLE_VERSION ${PROJECT_VERSION}
    MACOSX_BUNDLE_SHORT_VERSION_STRING ${PROJECT_VERSION_MAJOR}.${PROJECT_VERSION_MINOR}
    MACOSX_BUNDLE TRUE
    WIN32_EXECUTABLE TRUE
)

install(TARGETS untitled2
    BUNDLE DESTINATION .
    LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR}
    RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR}
)

if(QT_VERSION_MAJOR EQUAL 6)
    qt_finalize_executable(untitled2)
endif()

But could not succeed and obtained this error:

Running C:\Program Files\CMake\bin\cmake.exe -S C:/Users/jason/Documents/untitled2 -B C:/Users/jason/Documents/build-untitled2-office651-Debug in C:\Users\jason\Documents\build-untitled2-office651-Debug.
CMake Error at CMakeLists.txt:3 (project):

-- Configuring incomplete, errors occurred!
CMake process exited with exit code 1.

Is it because I have chromium's source code installed on my computer at the same time? I remember that since I compiled the Chromium source code, Qt's CMake doesn't work properl

Hi,

What does the error say ?

Something that is indeed strange is that the Ninja version used seems not to be the one provided with Qt. This might be the culprit.

@SGaist said in Qt CMake Project can not build:

CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_ASM_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!
CMake Error at qtbase/cmake/QtProcessConfigureArgs.cmake:965 (message):
  CMake exited with code 1.

How should I fix it?

SGaist

Isn't that a different error that before ?

Do you have your PATH environment variable changed since you build chromium ?

Are you using Qt Creator to build your application ?

ZeusFa

@SGaist

the some error.

Yes, I modified the Path, but I have now deleted the Path about Chromium
But this error still exists.

SGaist

Where did you delete it ?

Also check the Build part in the Project panel.

ZeusFa

@SGaist

see

Do I need to change here?

SGaist

Check the environment variables. Ninja should work fine, one of the main issue seems to be that it finds the one from chromium rather than the one you installed alongside Qt.

ZeusFa

@SGaist So far still not resolved

SGaist

@ZeusFa what is in Build Environment ?
