You are using very old CMake 3.9 which has no idea about Boost 1.65
https://github.com/Kitware/CMake/blob/v3.9.0/Modules/FindBoost.cmake#L769

Rule #1: Use latest version of CMake, ALWAYS!

There is absolutely no reason or excuse to not to use the latest as there are
- deb packages available https://apt.kitware.com/
- generic installer for any Linux and Windows

Updating CMake is easy-peasy for us lazy programmers with a bit of scripting:
https://github.com/mloskot/wsl-config/blob/master/scripts/install-cmake-latest.sh
https://github.com/mloskot/wsl-config/blob/master/scripts/install-cmake-latest.ps1
