Hi,
I have been using the CMake find_package()-function to set the
RTK_LIBRARIES variable in order to link my application with RTK, rtkcuda
etc.
I noticed that RTK_LIBRARIES also contains the paths to the CUDA libaries:
cuda, cudart, cufft, cublas.
I have had some problems with this, since my application (forced by a bug
in FindCUDA for my CMake-version) needs to link with the static CUDA
libraries, while RTK links with the dynamic (or static, I am not sure).
Regardless, I end up with duplicate symbols for some cuda runtime API
functions when linking with ${RTK_LIBRARIES} and ${CUDA_LIBRARIES} for my
application.
So, the general question is: Should third-party libraries be included in
the variable XXX_LIBRARIES after running find_package?
I am not sure, but I believe not. The patch below in RTK fixed the problems
for me. Then, of course, I need to always link with CUDA from my
independent project (an application in my case) when linking with RTK. But
I guess that's the way it is typically done.
