It looks like those are the same warnings we got before, many of which
I've fixed in git.

The OpenGL deprecations look like they'll need some non-trivial
rewriting to address, but aren't a problem for now.

Yes, you'll need builds for the same architecture of all the libraries
used.  You could instead have a 64-bit wx build and build Survex 64-bit,
but it's probably much quicker to rebuild proj than wx.

Currently libproj is a hard requirement because the GPX export code
tries to use it unconditionally.  We could just disable this code if
libproj isn't present, though the plan is to soon add support for
setting the grid which the data is in, at which point it probably
doesn't make sense to allow building without libproj.
