Question

我无法解决我遇到的一个特定问题：我无法确定罪魁祸首。

系统：Jetson TX1，arm64内核，32b用户空间，opencv4tegra

情况：一直在使用以下方式构建项目：

find_package( OpenCV )

这种方法很好并且编译好了。

错误：我是从源码构建并安装了CMake 3.5.2。现在我不再构建任何依赖OpenCV的项目了。我收到了无法找到的链接器错误：

opencv_dep_cudart

我假设问题是由OpenCVCConfig.cmake引起的，在这一点上：

# Import target "opencv_core" for configuration "Release"
set_property(TARGET opencv_core APPEND PROPERTY IMPORTED_CONFIGURATIONS RELEASE)
set_target_properties(opencv_core PROPERTIES
  IMPORTED_LINK_INTERFACE_LIBRARIES_RELEASE "opencv_dep_cudart;opencv_dep_nppc;opencv_dep_nppi;opencv_dep_npps;dl;m;pthread;rt;tbb"
  IMPORTED_LOCATION_RELEASE "${_IMPORT_PREFIX}/lib/libopencv_core.so.2.4.12"
  IMPORTED_SONAME_RELEASE "libopencv_core.so.2.4"
  )

文件外：/usr/share/OpenCV/OpenCVModules-release.cmake

但是，此文件在CMake版本之间不会更改，因为它是OpenCV文件。所以这必须是它的处理方式。

手动将我的CMake恢复到2.8.12.2允许我再次构建。以下是使用OpenCV的make命令的示例。请注意正确的cuda libs：

思考？我希望能够将更新的CMake保留在我的系统上，但是不太了解解决问题。如果你认为这个系统太独特了，我会撤回这个问题。

Answer 1

正如Michael Mairegger所说，你必须通过

来编译构建目录

sudo cmake .. -DCUDA_USE_STATIC_CUDA_RUNTIME=false

但我注意到的另一件事是，如果我之后尝试make，除非我执行cmake命令两次，否则它将无法工作。

OpenCV与CMake版本3.5.2对比CMake 2.X.X
