سلام من می خام با استفاده از cmake، opencv رو کامپایل کنم ولی خطاهای زیر رو گرفتم:

CMake Warning (dev) in samples/cpp/CMakeLists.txt:
Policy CMP0020 is not set: Automatically link Qt executables to qtmain
target on Windows. Run "cmake --help-policy CMP0020" for policy details.
Use the cmake_policy command to set the policy and suppress this warning.
This warning is for project developers. Use -Wno-dev to suppress it.

ممنون از راهنماییتون
