 One advantage of the CMake build system is that it covers both Unix and Windows builds. 
 The same set of {\tt CMakeLists.txt} files as above allows building ORE on Windows. The following instructions use the {\tt Ninja} build system ({\url{ninja-build.org}) that covers the role of {\tt make} on Unix systems and calls the Visual Studio C++ compiler and linker.
