Hello! I am testing out the CUDA support in CMake 3.8.0-rc2.
When running `make VERBOSE=1` in the build directory, I get a warning generated related to the GPU architecture flags for nvcc: ``` [ 80%] Linking CUDA device code /home/nwh/git/foobar/build/exec/CMakeFiles/exec.dir/cmake_device_link.o cd /home/nwh/git/foobar/build/exec && /usr/local/bin/cmake -E cmake_link_script CMakeFiles/exec.dir/dlink.txt --verbose=1 /usr/local/cuda/bin/nvcc -Xcompiler=-fPIC -shared -dlink CMakeFiles/exec.dir/exec.cc.o -o CMakeFiles/exec.dir/cmake_device_link.o ../libfoobar.a nvcc warning : The 'compute_20', 'sm_20', and 'sm_21' architectures are deprecated, and may be removed in a future release (Use -Wno-deprecated-gpu-targets to suppress warning). ``` I don't get the warning when the executable source is being compiled because an up-to-date architecture is specified: ``` [ 60%] Building CUDA object exec/CMakeFiles/exec.dir/exec.cc.o cd /home/nwh/git/foobar/build/exec && /usr/local/cuda/bin/nvcc -I/home/nwh/git/foobar -arch compute_30 -std=c++11 -x cu -c /home/nwh/git/foobar/exec/exec.cc -o CMakeFiles/exec.dir/exec.cc.o ``` Link to sample project: https://github.com/nwh/foobar Questions: * Is this a problem? * What is the purpose of cmake_device_link.o?
