+CMAKE USAGE:
+
+CMake support is provided via the CMakeLists.txt files.  Assuming you have CMake installed on your system, a typical usage would involve the following steps (from within the parent distribution directory):
+
+mkdir _build_
+cd _build_
+cmake <path to CMakeLists.txt usually two dots> <options> e.g. cmake .. -DAUDIO_WINDOWS_WASAPI=ON
+
+
+WINDOWS:
 
 The DirectSound and ASIO APIs in RtAudio compile with either the MinGW compiler or MS Visual Studio.  The WASAPI API currently only compiles in MS Visual Studio.
