I agree, that using the packaged libs would save us further trouble.

But I once had an issue with a packaged version of pthread and linking
my app against mxe's pthread at the same time because of multiple
definition of the symbols.
So I looked in the source:
All libraries which I used (expat, freetype, hdf5, jpeg, libxml2,
theora, png, tiff and zlib) contain a vtk_libname_mangle.h which
prefixes all exported symbols.

So I guess there should be no multiple symbol definitions because of vtk.

The only reason left for using mxes system libs would be bugfixes, which
I think don't outweigh the problem of keeping vtk compatible with mxe's
up-to-date libs.

But could you at least merge the change in src/vtk6-1-tryrun.patch for
the CMAKE_REQUIRE_LARGE_FILE_SUPPORT output?
