+
+to fix warning
+
+CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
+  Compatibility with CMake < 3.5 will be removed from a future version of
+  CMake.
+
+  Update the VERSION argument <min> value or use a ...<max> suffix to tell
+  CMake that the project does not need compatibility with older versions.
