CMake configure error when using submodules on `develop`

[samuelpmishLLNL]

When configuring serac with ENABLE_CODEVELOP on the develop branch, CMake emits the error:

...
[cmake] -- Serac Code Checks: ON
[cmake] -- Configuring done
[cmake] CMake Error: install(EXPORT "serac-targets" ...) includes target "cuda" more than once in the export set.
[cmake] -- Generating done
[cmake] CMake Generate step failed.  Build files cannot be regenerated correctly.

#748

CUDA builds have not been enabled for codevelop. Referencing these together so we can fix them all at once.
