cuda 9.1 和 eigen手动适配 - 好文

计算机视觉应用中，经常用到eigen库，也会用到cuda库，因为eigen库没有及时follow cuda的更新，导致cuda
9.0和9.1最新的版本，会出eigen兼容问题，报错如下：
note：如果使用cmake build，注意下面的顺序，一定放到include_directories开始

include_directories(${CUDA_INCLUDE_DIRS})

include_directories(${EIGEN3_INCLUDE_DIRS})

因为eigen是头文件自包含的lib；对于装有多个eigen版本，或者使用其他版本eigen的库，一样会有问题
