when I was compiling your CBCT reconstruction software - I thought it was due me having a different version of CUDA.<br>I solved it by changing the cmakelists.txt to use a FindCuda_wrap.cmake and associated files (copied and slightly modified from the rtk one.) to let those files do the linking.<br>I also changed the CMakelists.txt to make it compile on non-cuda hardware, so I'm not completely sure whether this might have been the solution to that.<o:p></o:p></p><p>Attached in zip archive. :: My current CBCTrecon -> <a

OpenCL code in my own <a href="https://github.com/agravgaard/RTK.git">fork</a>), but I don't think that made any difference in the linking. <o:p></o:p></p><p>Best
