Which platform are you working on? If you need a fully static compilation
of everything *all* the way down including openssl + zlib + zstd + libtiff
+ all the other libraries, using vcpkg[1] might be a reasonable approach.
By default it does static compilation on macOS & Linux, and it has a static
compilation option on Windows (the default on Windows is dynamic). It
doesn't support every compile option though, but it's customisable and if
you're after a reasonably vanilla GDAL it should work ok.

Note that GDAL + Proj (maybe others), have data files they rely on, so
while you may be able to get a single executable, you'll still need to
distribute these files. I can imagine ways around that, but they're getting
fairly complex.

Can you share the process you've currently got to?
