我在 2019 64 位版本中使用 MSVC 為帶有 Qt 的 Windows 編譯 openCV。
在啟動第一個配置時，我得到一些錯誤串列，如下所示：
Check size of size_t
CMake Error at C:/Program Files/CMake/share/cmake-3.25/Modules/CheckTypeSize.cmake:147 (try_compile):
Cannot copy output executable
''
to destination specified by COPY_FILE:
'C:/Users/alejandro/Downloads/opencv/build/CMakeFiles/CheckTypeSize/SIZEOF_SIZE_T.bin'
Recorded try_compile output location doesn't exist:
C:/Users/alejandro/Downloads/opencv/build/CMakeFiles/CMakeScratch/TryCompile-jglvcw/Debug/cmTC_e9d0b.exe
Call Stack (most recent call first):
C:/Program Files/CMake/share/cmake-3.25/Modules/CheckTypeSize.cmake:277 (__check_type_size_impl)
3rdparty/libjpeg-turbo/CMakeLists.txt:25 (check_type_size)
有誰知道我該如何解決這個問題？

我已經看到另一個重要的錯誤是與 OpenMP 相關的：

uj5u.com熱心網友回復：
我遇到了同樣的問題，是 CMake-3.25.0-rc2 故障，將其更改為 3.24.2 即可。
