add note about GDAL building issues on Windows

[vlandau]

Some Omniscape users had this problem. Just thought I'd add text to provide some guidance. See Circuitscape/Omniscape.jl/issues/47

@ranjanan please merge if it looks okay -- just a simple addition to the readme.

My suggestion is that we just wait for GDAL.jl folks to tag a new version and update our dependencies.

My suggestion is that we just wait for GDAL.jl folks to tag a new version and update our dependencies.

Okay -- We don't have a compat entry for GDAL since we depend on ArchGDAL (which of course itself depends on GDAL), but I think this is solved with ArchGDAL v0.4.0 which was just released. See yeesian/ArchGDAL.jl#125

I added v0.4 to the compat, but we could also remove ArchGDAL of 0.3.1 to prevent this issue altogether.

Let's keep moving forward on versions.

[vlandau]

I'll close this. I can do direct commit to master to update the ArchGDAL compat if that works?

[vlandau]

I think we just need to change the compat to v0.4.0 for ArchGDAL.

I just realized my comment was wrong and deleted it. Yes, we should do that - so that we are able to use artifacts.

[vlandau]

Okay I'll make that commit now!

[vlandau]

Ha! You beat me to it 🙂

[ViralBShah]

:-) I also updated IterativeSolvers.jl. Seems to pass things for me - but can you give it a try?

I think these old versions were holding back many dependencies to old versions. This should resolve more dependent packages to use newer versions.

[ViralBShah]

Just bumped AlgebraicMultigrid too.

[vlandau]

Install working fine on my Linux machine 👍

[ViralBShah]

Let's give it a few days on master and then tag a new version. Do the omniscape tests pass with this?

[vlandau]

I'll test it out now!

Ah, we changed RasterMeta internally in Circuitscape so I just need to make a slight update. I'm going to update the Circuitscape dep to 5.6.0 soon,too, and switch to the CS versions of read_raster and write_raster.
