hi all,<br><br>I'm beginning to migrate all my codes to use cmake and I seek your help. I apologize in advance if this is a trivial question.<br><br>I'm using Ubuntu 7.10 with cmake 2.4. I'm trying to compile a project called vtkCuda that integrates NVidia's CUDA volume rendering techniques into vtk. The file repository is located at http://www.na-mic.org/svn/Slicer3/branches/cuda/Modules/VolumeRenderingCuda. The current CMakeLists.txt works under Windows but appears to be quite buggy under linux. It also has a lot of un-needed dependencies (on slicer3d); for my personal interests, I just want to get it to work with vtk. The only true dependency is CudaSupport, located at http://www.na-mic.org/svn/Slicer3/branches/igt_cuda_merge/Libs/CudaSupport/.<br><br>CudaSupport itself requires NVidia's CUDA library and SDK and I have managed to compile it without any major issues. The CMakeLists.txt for CudaSupport defined a few variables (mostly boolean) that are needed by vtkCuda's CMakeLists.txt. One of such variable is CUDA_SUPPORT_ENABLED; after the successful compilation of CudaSupport, during the ccmake stage of vtkCuda it complains about CUDA_SUPPORT_ENABLED is not defined.<br><br>My eventual goal is to rewite the CMakeLists.txt for vtkCuda so that is only depends on the successfufl compilation of CudaSupport (and not Slicer3D). My questions are:<br><br>how do I make ccmake to determine the variables set by CudaSupport, and to find CudaSupport's headers/libraries, in the CMakeLists.txt for vtkCuda? Or, how to I "export" the variables set by the successful compilation of Cudasupport?<br><br>ps. I'm not the developer for vtkCuda/CudaSupport, merely a user trying to use it for my own projects.<br><br>Thank you,<br><br><br><br><br><br /><hr /> <a href='' target='_new'></a></body>
