DataSmith Importer Format Option

Some formats of DataSmithImporter are not available on 4.26 source builds.
CADLibrary::CTKIO_InitializeKernel() fails in ICADInterfacesModule::GetAvailability() inside the FDatasmithCADTranslator:Initialize function. It is normally available in the binary version, and Format such as dwg, igs, and igs is available.
Please help me with the solution.

our agreement with the third party provider for CAD import does not allow us to distribute their library with the source code. Thus, you cannot build full CAD import functionality from source.
