Bonjour,

je suis sur Linux et j'essaye de build un programme simple en C++ utilisant Qt avec CMake mais j'ai l'erreur suivante:

CMake Error: Could not find cmake module file: CMakeDetermine1.0.0Compiler.cmake
CMake Error: Error required internal CMake variable not set, cmake may not be built correctly.
Missing variable is:
CMAKE_1.0.0_COMPILER_ENV_VAR
CMake Error: Error required internal CMake variable not set, cmake may not be built correctly.
Missing variable is:
CMAKE_1.0.0_COMPILER
CMake Error: Could not find cmake module file: /home/nomdutilisateur/Documents/monprojet/build/CMakeFiles/3.26.4/CMake1.0.0Compiler.cmake
-- The CXX compiler identification is GNU 13.1.1
CMake Error at CMakeLists.txt:3 (project):
  No CMAKE_1.0.0_COMPILER could be found.

  Tell CMake where to find the compiler by setting the CMake cache entry
  CMAKE_1.0.0_COMPILER to the full path to the compiler, or to the compiler
  name if it is in the PATH.


CMake Error: Could not find cmake module file: CMake1.0.0Information.cmake
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Check for working CXX compiler: /usr/bin/c++ - skipped
-- Detecting CXX compile features
-- Detecting CXX compile features - done
CMake Error: CMAKE_1.0.0_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!

Pourtant, mon compilateur (gcc) est bel et bien installé.

Voilà le contenu du fichier CMakeLists.txt au cas où:

cmake_minimum_required(VERSION 3.1.0)

project(helloworld 1.0.0 LANGUAGES CXX)

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

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

if(CMAKE_VERSION VERSION_LESS "3.7.0")
    set(CMAKE_INCLUDE_CURRENT_DIR ON)
endif()

find_package(Qt5 COMPONENTS Widgets REQUIRED)

if(Qt5Widgets_FOUND)
    message("Qt5 not found")
endif()

add_executable(helloworld
    ui/mainwindow.ui
    src/mainwindow.cpp
    main.cpp
)

target_link_libraries(helloworld Qt5::Widgets)

Merci d'avance pour votre réponse.
