    Add workaround for VS6.
    
    VS6 fails to lookup protected class definitions in a parent class.  The
    workaround is to make them public instead only when compiling for VS6.

    Use containers of labeled search paths instead of individual members
    
    Manage classes of search paths in labeled containers.  This removes the
    need to have a seperate member variable for each type of search path, but
    also allows path types to be grouped togethor in various different ways
    and manipulated as subsets of the full set of search paths.

commit 3c85babcd9d1ba0f0da9b0818063a0b71dfc18d8
Author:     Chuck Atkins <chuck.atkins at kitware.com>
AuthorDate: Wed Oct 15 16:36:42 2014 -0400
Commit:     Chuck Atkins <chuck.atkins at kitware.com>
CommitDate: Tue Oct 28 16:56:38 2014 -0400

    Encapsulate search path manipulation functions into a seperate class.
    
    The functions for adding the various different types of paths have been
    factored out into a new class, cmSearchPath.  It is to be used as a helper
    container class for the various find_* commands.

CommitDate: Tue Oct 28 16:56:38 2014 -0400

    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.
