_CMAKE_CUDA_WHOLE_FLAG issue

Reproduce the command with CMAKE_CXX_COMPILER and CMAKE_CUDA_COMPILER set to /usr/bin/circle. Start at CMakeLists.txt:222 and the CMakeDetermineCompilerABI.cmake and CMakeTestCUDACompiler.cmake paths shown in the error. Done means establishing a supported way to use the alternate compiler for the CUDA configuration, or documenting why it cannot be used.

I'm trying to point circle at the nvexec tests. This is what I'm getting:

$ cmake -DCMAKE_CXX_COMPILER=/usr/bin/circle -DCMAKE_CUDA_COMPILER=/usr/bin/circle -DSTDEXEC_ENABLE_CUDA=ON ..

CMake Error: Error required internal CMake variable not set, cmake may not be built correctly.
Missing variable is:
_CMAKE_CUDA_WHOLE_FLAG

How do I force stdexec to use a different compiler as if it were nvc++?
