You can refer to this issue , which works for me.你可以参考这个问题，这对我有用。 My problem is solved by set -DWITH_V4AL=OFF and -DWITH_LIBV4L=ON我的问题是通过设置-DWITH_V4AL=OFF和-DWITH_LIBV4L=ON

After I set WITH_V4L = OFF but still keep WITH_LIBV4L = ON, the configuring skipped the searching of 'sys/videoio.h', and the compilation worked.在我设置 WITH_V4L = OFF 但仍然保持 WITH_LIBV4L = ON 后，配置跳过了“sys/videoio.h”的搜索，并且编译工作。
