@blowekamp This looks like a good example to have.

@blowekamp This should probably default to InsightSoftwareConsortium rather than blowekamp organization.

Yes, it is dependent PR #5721 for the modular interface libraries.

OK for DRAFT pr, but should this default to "main" or "v5.4.5" or "latest"? as the default?

At least during development, it may be best to use a variable that points to the current git hash... This may get tricky with source distributions and keeping this directory independent of the ITK CMAkE environment.
So...likely "main" is the best option.
By use FetchContent for ITK, along with specific ITK module interface library linking enable to build only the targets needed in ITK for a project. While the initial configuration time is longer due to downloading and configuring ITK, the CMake project structure is simpler than a Superbuild, and the build is more efficient.

This is a standalone directly that can be build separately to try out this combination of feature to build a project/executable with ITK.
