[gdal-dev] Building GDAL with autoconf for Android on Windows

[Andrew Patterson]

My options are rather limited unfortunately. I'd love to bump our GDAL from
3.3.0 to 3.5.0+ to pick up the CMake, but I'm not able to do that right
now. So I'm stuck building it for Android in Git bash with the pre-Cmake
options.

That said, in the end, I've given up on building it this way. I suspect it
works just fine and all my problems are related to Git bash's trouble with
spaces. We were using a custom CMake file I was hoping to avoid using, but
after three solid days of bashing my head against this, I'm throwing in the
towel and I'll just roll my own temporary CMake. Which I guess is what you
were suggesting anyways!

Thanks for the input. It helped tip me over into doing the manual CMake
thing. I can't wait to throw it away and use the 'out-of-the-box' version,
but that may be a few months away :P
