ERROR IN THE QTCREATOR, RELATED TO CMAKE AUTO SETUP CONFIG

Amirreza Taghizadeh

Hello,

I've encountered a very strange bug or whatever it might be called. When I create a new Qt widget or Qt console or any project in Qt-creator, the cmake initialization gives me the following errors,

[cmake] Running C:\Qt\Tools\CMake_64\bin\cmake.exe -S C:/Users/Asus/Projects/untitled4 -B C:/Users/Asus/Projects/untitled4/build/Desktop_Qt_6_7_3_MSVC2019_64bit-Debug in C:\Users\Asus\Projects\untitled4\build\Desktop_Qt_6_7_3_MSVC2019_64bit-Debug.

[cmake] 
[cmake] Elapsed time: 00:00.

However, when I Unset the CMAKE_PROJECT_INCLUDE_BEFORE variable from the current configuration, the error disappears. I have already uninstalled and reinstalled Qt several times. How can I delete this variable from the current configuration by default, so that I don't have to unset it every time I create a project in QT?

What version of Qt Creator wrote the CMakeLists.txt?
Have you modified it?

@Amirreza-Taghizadeh Go to Qt Creator > Preferences > CMake > General and unselect Package manager auto setup.

Your project has two errors:

project could not find requested file:
C:/Users/Asus/Projects/untitled4/build/Desktop_Qt_6_7_3_MSVC2019_64bit-Debug/.qtc/package-manager/auto-setup.cmake
CMake Error at C:/Qt/Tools/CMake_64/share/cmake-3.29/Modules/FindThreads.cmake:66 (message):
FindThreads only works if either C or CXX language is enabled

The first error is due to the missing .qtc/package-manager/auto-setup.cmake which should be copied by Qt Creator before running CMake to configure your project.

The second error, is weird, as if your project doesn't have the C and CXX languages declared.

How does your project() function call at CMakeLists.txt:3 looks like?
