_CMAKE_CUDA_WHOLE_FLAG issue

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
CMake Error at /usr/local/share/cmake-3.26/Modules/CMakeDetermineCompilerABI.cmake:57 (try_compile):

-- Configuring incomplete, errors occurred!

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

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.
