+Note to authors of FindXXX.cmake files
+
+We would like all FindXXX.cmake files to produce consistent variable names.
+
+XXX_INCLUDE_DIR, 	Where to find xxx.h, etc.
+XXX_LIBRARIES, 		The libraries to link against to use XXX. These should include full paths.
+XXX_DEFINITIONS, 	Definitions to use when compiling code that uses XXX.
+XXX_EXECUTABLE, 	Where to find the XXX tool.
+XXX_YYY_EXECUTABLE, 	Where to find the YYY tool that comes with XXX.
+XXX_ROOT_DIR, 		Where to find the home directory of XXX.
+XXX_FOUND, 		Set to false if we haven't found, or don't want to use XXX.
+
+
+You do not have to provide all of the above variables. You should provide XXX_FOUND under most circumstances. If XXX is a library, then XXX_INCLUDE_DIR, XXX_LIBRARIES, and XXX_DEFINITIONS should also be defined.
+
+Try to keep as many options as possible out of the cache, leaving at least one option which can be used to disable use of the module, or find a lost library (e.g. XXX_ROOT_DIR)
+
+If you need other commands to do special things (e.g. the QT_WRAP_UI setting in FindQt.cmake) then it should still begin with XXX_. This gives a sort of namespace effect.
