I believe the closest equivalent to settinga CUDA_TOOLKIT_ROOT_DIR when using enable_language(CUDA) is to set either the environment variable CUDACXX or the CMake cache entry CMAKE_CUDA_COMPILER to point to the location of the nvcc compiler.
However I think there are still some "features" of FindCUDA that enable_language don't support, e.g. variables and/or import targets with locations, see https://gitlab.kitware.com/cmake/cmake/issues/17816 Kind regards, Luis On Fri, Mar 29, 2019 at 4:57 PM Dustyn Blasig <[email protected]> wrote: > "we should not try to combine enable_language(CUDA) with > find_package(CUDA).
