 [**Windows**] On Windows you have to explicitly tell CMake to target 64-bit
 architecture by adding the `-DCMAKE_GENERATOR_PLATFORM=x64` option to the
 cmake invocation (`cmake -DCMAKE_GENERATOR_PLATFORM=x64 ..`). 32-bit builds 
 are not supported at the moment.

 Set the build type. The most important ones are Debug and Release.
