The following error message may be encountered when building CUDA code with CMake:

error LNK2019: unresolved external symbol __cudaRegisterLinkedBinary

It is caused by generated glue code not being linked in. The glue code is generated into files named with the project and a suffix:

myprojectname.device-link.obj

Ensure CUDA is enabled as a language for the project:
