CMake找不到OPENMP(Mingw、Win10、VSCODE)

Question

我正在努力在Win10上使用OpenMP编译一个项目。我的c++项目在VSCODE上，我使用的是MINGW32。错误是：

-- Could NOT find OpenMP_C (missing: OpenMP_C_FLAGS OpenMP_C_LIB_NAMES)
-- Could NOT find OpenMP_CXX (missing: OpenMP_CXX_FLAGS OpenMP_CXX_LIB_NAMES)
-- Could NOT find OpenMP (missing: OpenMP_C_FOUND OpenMP_CXX_FOUND)
-- Configuring done
-- Generating done
-- Build files have been written to:F:.../build

与在项目中搜索OpenMP相关联的CMakeLists文件如下：

cmake_minimum_required(VERSION 3.10)
project(RayTracing)

set(CMAKE_CXX_STANDARD 17)
set (CMAKE_FIND_ROOT_PATH C:/MinGW)

message(STATUS "Checking OpenMP")
find_package(OpenMP)
IF(OPENMP_FOUND)
    message("Found OpenMP! ^_^")
    # add flags for OpenMP
    set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")
    set(CMAKE_SHARED_LINKER_FLAGS "${CMAKE_SHARED_LINKER_FLAGS} ${OpenMP_SHARED_LINKER_FLAGS}")
    set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS}  ${OpenMP_EXE_LINKER_FLAGS}")
    target_link_libraries(RayTracing PUBLIC OpenMP::OpenMP_CXX)
ELSE()
    message("Missed OpenMP! x_x")
ENDIF()

set(SOURCE_FILES main.cpp)

add_executable(RayTracing ${SOURCE_FILES})

是的，我已经搜索了互联网上几乎所有的帖子。但它们都是关于MacOS和clang的。我找不到解决我的问题的办法。有什么想法吗？求求你我真的需要帮助。

你还在用旧的MinGW吗？你真的应该改用MinGW-w64。

来自http://winlibs.com/的MinGW-w64构建附带了OpenMP。
