Hi Clint,
In my case, it wasn't anything like that. I was only specifying
/usr/local/cuda/lib once. More specifically, my CMakeLists.txt specified
TARGET_LINK_LIBRARIES(${SHARED_TARGET} ${CUDA_LIBRARIES})
where CUDA_LIBRARIES is
/usr/local/cuda/lib/libcudart.dylib-Wl,-rpath-Wl,/usr/local/cuda/lib
This library also linked against another of my libraries, that also happened to
link against CUDA. So that's why it was getting referenced twice: once
directly, and once indirectly via a second library.
In any case, it's not clear to me why CMake is calling "install_name_tool
-delete_rpath". Everything works fine without doing that. And when you do it,
that breaks things.
