You need to tune your build so it finds KEALib. See 
https://gdal.org/development/building_from_source.html#kea for related 
CMake options. "grep GDAL_USE_KEACMakeCache.txt" should report ON if 
things are proprerly configured. Once the driver is available in your 
GDAL build, just changing the name of the driver should be sufficient

See also 
https://github.com/OSGeo/gdal/blob/master/.github/workflows/ubuntu_20.04/build-deps.sh#L30 
for an example of a CI configuration that builds with libkea support 
(not much to do if you install it in a standard location looked for by 
cmake)
