To build on non-Unix systems (Windows / Visual Studio) see CMake documentation on generators. The necessary steps are something like the following:
mkdir build
cd build
cmake -G "Visual Studio 16 2019" ..
# The above will generate a solution file for Visual Studio.
# Now open the generated solution file in Visual studio and build the project.
