这是opencv_videoio.dir中的build.make（第59〜63行）

因为似乎没有人与我有相同的症状，所以我尝试手动修复它。 但是，我找不到这行的语法问题。
cd /d D:\opencv-build\modules\videoio && C:\MinGW\bin\g++.exe $(CXX_DEFINES) $(CXX_INCLUDES) $(CXX_FLAGS) -Winvalid-pch -include "D:/opencv-build/modules/videoio/precomp.hpp" -o CMakeFiles\opencv_videoio.dir\src\videoio_registry.cpp.obj -c D:\opencv\sources\modules\videoio\src\videoio_registry.cpp
我检查了D:/opencv-build/modules/videoio/precomp.hpp存在。
我只想检查是否有什么线索可以解决我的问题。
