FindCUDAToolkit: Fails to locate nvToolsExt, no error nor warning

I'm trying to build my cuda-api-wrappers repository on Windows machines. Specifically, I'm using a GitHub actions runner VM, running Windows 10, with MSVS 2019. My CMakeLists.txt has the following relevant parts (edited for brevity):

PROJECT(cuda-api-wrappers
(snip)
	LANGUAGES CUDA CXX)
(snip)
find_package(CUDAToolkit REQUIRED)
(snip)
target_link_libraries(nvtx INTERFACE CUDA::cudart)
(snip)
target_link_libraries(nvtx PRIVATE CUDA::nvToolsExt)

The configuration fails; the logs are available here, but here are the relevant parts:

CMake Error at CMakeLists.txt:39 (add_library):
  Target "nvtx" links to target "CUDA::nvToolsExt" but the target was not
  found.  Perhaps a find_package() call is missing for an IMPORTED target, or
  an ALIAS target is missing?

I'm certain CMake should have found CUDA::nvToolsExt under these circumstances. But even if somehow it failed locating the relevant headers/libraries - it should either fail in finding the CUDA toolkit, or warn about only partially finding it. Neither of these happen.

As for the error log, the only suspicious parts are:

... and I wouldn't be able to deduce from this that there's any trouble with nvToolsExt.
