Build Error: "Skipping maps since Boost was not found" and CMake Error: {..}used in this project, but they are set to NOTFOUND.

Hello,

Please, why is there no mention of Boost dependency in the documentation!

I have Boost installed and I have tested it with a simple program that uses boost::array and it's fine.

My environment: CentOS 8, 64-bit, Cmake 3.11.4, Boost 1.66

I am getting this error when I trying to build as described in the documentation. My Ubuntu VM is also giving the same issue.

$ cmake --config Debug "-DCMAKE_BUILD_TYPE=Debug" .. results in this:
