+  This build system supports two ways to build binaries for Windows.
+
+  1. Building on Windows using MSVC.
+  Implementation notes:
+  - /DWIN32 and /D_WINDOWS definitions are included into the CMAKE_CXX_FLAGS_INIT
+    and CMAKE_CXX_FLAGS_INIT variables by default.
+  - A run-time library is selected using the CMAKE_MSVC_RUNTIME_LIBRARY variable.
+  - MSVC-specific options, for example, /Zc:__cplusplus, are additionally required.
+
+  2. Cross-compiling using MinGW.
+  Implementation notes:
+  - WIN32 and _WINDOWS definitions must be provided explicitly.
+  - A run-time library must be specified explicitly using _MT definition.
