Don't know.

It looks like vcpkg has a GDAL package:

https://vcpkg.io/en/packages.html

search for GDAL:

gdal |Version: 3.4.1

vcpkg should install everything you need to get GDAL up and running.

vcpkg is pretty straightforward to use.

vcpkg builds every from scratch. It's pretty nice.

It will compile all of the dependencies, it will even download ming and
compile away.

So lot of fuzz about GDAL? It is a translator library for raster and vector
geospatial data formats and is released as open source. Yes it has ton
of dependencies and all of those are open source as well. Does the
Skybuck want to write all such transformations himself?

I am not sure why the Skybuck wants to work with GDAL, he mentioned
Aliens? ;^)

It's just nice that its on the list of packages provided by vcpkg.

Converting spherical into Cartesian form?
