This was fixed last Monday, so already checked in.

I think the right way to solve this one is to add the include of the
local directory into the build rather than change the <> to "".  The
code you've changed is provided by Terrex and the next code drop they
provide will have the <> in it and therefore break the build once
more.  This should just require a tweak of the txp/CMakeLists.txt
file.

Thanks now merged and submitted to SVN.  I also fixed the Cygwin path
as it had a similar problem.  I do think that both paths are still
wrong though - the plugins shouldn't have a cyn or lib prefix really,
they are plugins, they should just be compiled as osgdb_ext.lib/.dll.
 Cygwin and Mingw contributors have in the past have chosen the
different naming, I don't know the original motivation though nor
whether it still applies to today.

This is another Win32/Mingw specific issue, a tweak to the
CMakeModules files are all that should be required.  I don't know off
hand which bit to tweak though.

Great to hear, thanks for the feedback.
