CMake looks for some particular flags from nvcc -v *.cu to setup the required variables. However they cannot be found and the configuration stage fails. Is this something on this package side or is this set by NVIDIA? I'm running the lat...
For anyone stumbled upon this question, here is the final CMakeLists.txt file I've used: cmake_minimum_required(VERSION 3.5.1) set(CMAKE_CUDA_COMPILER /usr/local/cuda-9.2/bin/nvcc) project(train) include(FindCUDA) set(CMAKE_CXX_STANDARD 14) find_package( OpenCV REQU...
<I want to build opencv 4.4 with cuda on ubuntu 18.04, while, when I cmake, it shows that: "CMake Warning at cmake/OpenCVFindLibsPerf.cmake:45 (message): OpenCV is not able to find/configure CUDA SDK (required by WITH_CUDA). CUDA support will be disabled in OpenCV build. To elim...
If you look into FindCUDA.cmake it clearly says that: The script will prompt the user to specify CUDA_TOOLKIT_ROOT_DIR if the prefix cannot be determined by the location of nvcc in the system path and REQUIRED is specified to find_package(). To use a different installed version of the ...

显然,CUDA编译器(nvcc)没有得到正确的链接,但我不确定这就是问题所在。这是我的CMakeLists.txt: cmake_minimum_required(VERSION 3.15) project(test_cuda LANGUAGES CXX CUDA) find_package(CUDA) set(CMAKE_CXX_STANDARD 17) add_executable(test_cuda main.cu) 我得到的结果如下: 浏览9提问于2020-01-...
