I don't know if the following is the correct advice, but I use the
following code in my setup to enforce Pascal:
string(APPEND CMAKE_CUDA_FLAGS " -gencode arch=compute_60,code=sm_60")
else my code would not compile once I started using some newer directives.
I believe that more archs would be needed in the string for better
support of newer architectures, but just to get the starting point.
I would have preferred if there was a better directive, similar to
set(CMAKE_CXX_STANDARD 14)
that can enable either C++14 or C++17 or later (depending on other
components of the project) without actually harcoding c++14 and ending
up with "-std=c++14 -std=c++20" in flags. For example something along
the lines of
set(CMAKE_CUDA_MIN_ARCH 60)
