+# CMake Targets
+CMake Targets decide what you are intending to build. Targets are (usually) a 
+specific system, like vita, 3ds, switch, or a specific OS with a library, e.g.
+targetting vulkan on linux vs targetting opengl on linux, or targetting opengl
+on windows, etc.
+
+In addition the target also decides what project(s) to build. Usually this is
+just the specific game and/or systems to be built, so if you are building a VN
+game the target would need to let the build system know you want to rollup the
+VN parts of the engine also.
+
+Note this is one of the very few build args that is required during the 
+configuration of cmake to make it build properly, failure to specify a target
+will result in a build error.
