Refactor and seperate search path construction for find commands

Prior to this commit, the set of search paths to traverse for find commands
was incrementally constructed.  This change allows each group of paths, i.e.
CMakeVariablePaths, UserHintsPaths, SystemEnvironmentPaths, etc. to be
constructed and manipulated independently, and then all combined togethor.
