target_link_libraries as replacement for xpTargetExtern, part 3

[smanders]

xpTargetExtern() has been a good boat and has helped get us to where we are today, but a better, more familiar boat exists (target_link_libraries()) now that I've discovered how to associate include directories and compile definitions with a library target

this issue is all about setting target properties and using a cmake namespace (xpro::) in externpro projects and is really a continuation of changes in the last release of externpro

linker errors on Windows for boost::iostreams (zlib) I have a boostio repo with a decompressor executable that I'm planning to add to wxInclude repo to catch this earlier in the future...
