+Subject: [PATCH] cmake_minimum_required() before project()
+
+ * Without this CMAKE_MSVC_RUNTIME_LIBRARY=MultiThreaded (MT) Windows builds still produced incompatible MultiThreadedDLL (MD) output.
+
+ * Resolves following warning:
+
+CMake Warning (dev) at CMakeLists.txt:2 (project):
+  cmake_minimum_required() should be called prior to this top-level project()
+  call.
+
+ * Use ${CMAKE_HOST_SYSTEM_NAME} as ${CMAKE_SYSTEM_NAME} not set before project().
