报错细节

用cmake编译Sophus库时，有类似如下报错

CMake Error at test/core/CMakeLists.txt:18 (ADD_EXECUTABLE):
  Target "test_sim3" links to target "CUDA::cublas" but the target was not
  found.  Perhaps a find_package() call is missing for an IMPORTED target, or
  an ALIAS target is missing?


CMake Error at test/core/CMakeLists.txt:18 (ADD_EXECUTABLE):
  Target "test_sim3" links to target "CUDA::cudart" but the target was not
  found.  Perhaps a find_package() call is missing for an IMPORTED target, or
  an ALIAS target is missing?

问题定位

有多个target报错，都是这四个CUDA库链接问题，但我检查CUDA配置没有什么问题，最后发现是Eigen库路径问题。

原Eigen路径：/usr/include，需要是usr/local/include

遂参考这篇博客，删除原Eigen（其实不删除，把原来文件复制到新目录应该也行）：

然后clone下来Eigen库，老老实实编译，路径就是对的了，然后再去编译Sophus库时，就没有错了。
