I'm attempting to use the following dependency to read a file in the DTED
format.
<dependency>
<groupId>org.geotools</groupId>
<artifactId>gt-imageio-ext-gdal</artifactId>
<version>20.1</version>
</dependency>
>From what I can tell, gt-imageio-ext-gdal is dependant on
>imageio-ext-gdalframework-1.1.27 which seems to require that I have the JNI
>bindings installed for GDAL 1.9.2.
Looking at the imageio-ext project, version 1.1.27 was released October of 2018
and does in fact include 1.9.2 native libraries in its release. However, all of
the precompiled binaries are for older OS versions. Redhat 6 is the newest OS
represented and I can't seem to find precompiled binaries anywhere for RHEL7 or
newer versions of Ubuntu.
I notice that GDAL is well past 1.9.2 and is already deploying version 2.2+ as
part of apt-get/yum, but using newer versions of the bindings does not appear
to work since I get this stack trace if I try.

Is there some other way of acquiring the bindings at this point, so people have
stopped deploying against newer OS or should is the normal process to compile
the bindings yourself?
