when I use websocktpp in my project, then comes camke version warning:
C/C++: debug|arm64-v8a :CMake Deprecation Warning at D:/Hippy/driver/js/android/.cxx/Debug/2e504n4g/arm64-v8a/_deps/websocketpp-src/CMakeLists.txt:5 (cmake_minimum_required):
C/C++: debug|arm64-v8a : Compatibility with CMake < 2.8.12 will be removed from a future version of
C/C++: debug|arm64-v8a : CMake.
C/C++: debug|arm64-v8a : Update the VERSION argument value or use a ... suffix to tell
C/C++: debug|arm64-v8a : CMake that the project does not need compatibility with older versions.
so should we upgrade cmake version to 2.8.12
