Incorrect CUDA Architecture detection

So I’ve been trying to generate the cmake project for Mitsuba 2 on Windows 10 (build: 19041.572) using the Visual Studio 16 2019 generator and x64 toolchain.

This is a project that requires CUDA and thus for the architecture specification, I set the flag CMAKE_CUDA_ARCHITECTURES flag to 75 which should be supported with CUDA SDK version 11.1.74 and my GPU (RTX 2070) that goes up to compute capability 7.5. Unfortunately, I’ve found that setting the CMAKE_CUDA_ARCHITECTURES flag to 75 leads to a fatal error whereupon CMakeDetermineCUDACompiler.cmake fails to detect this as a valid architecture. This gives the following error:

CMake Error at C:/Program Files/CMake/share/cmake-3.18/Modules/CMakeDetermineCUDACompiler.cmake:551 (message):
  The CMAKE_CUDA_ARCHITECTURES:

    75

  do not all work with this compiler.  Try:

    52

  instead.
Call Stack (most recent call first):
  ext/enoki/CMakeLists.txt:28 (enable_language)

Normally, I would consider this an error on my part as maybe I’ve misconfigured something, but when I set the architecture to 50 I encounter the exact same error which makes no sense considering that the CUDA SDK still supports compute capability 5.0.

Thus I dug further into where this error occurs and found that in CMakeDetermineCompilerId.cmake the Visual Studio + CUDA path (line 365 to 421) does not correctly set the architecture flags for the temporary project, build\CMakeFiles\3.18.4\CompilerIdCUDA\CompilerIdCUDA.vcxproj, generated from ${CMAKE_ROOT}/Modules/CompilerId/VS-${v}.${ext}.in. Essentially, in the call to

function(CMAKE_DETERMINE_COMPILER_ID_BUILD lang testflags userflags src)

the testflags and userflags are not correctly passed to the compiler when the ${CMAKE_GENERATOR} is any version of Visual Studio.

You can also see this by looking at the CMakeOutput.log generated during the project configuration:

Compiling the CUDA compiler identification source file "CMakeCUDACompilerId.cu" succeeded.

There are no other architecture specifications in this call to the compiler and I cannot identify another point in the CMake CUDA detection pipeline that would lead to a failure to detect 75 and 50 as valid architectures. In fact, the only architecture that is accepted is 52 which is the default tested in CMakeDetermineCompilerId.cmake.

If I am understanding this incorrectly or misusing the CMAKE_CUDA_ARCHITECTURES flag, I’d be curious to know exactly how I should specify the architecture.
