1. package failed: ndt_gpu
CMakeLists.txt:22 (AW_CHECK_CUDA)
解决：
cuda版本<=10.0
2. GPU support on Melodic requires Eigen version>= 3.3.7
默认的eigen安装位置在 /usr/include/eigen3 ，将/Downloads/eigen-3.3.7/install/include/eigen3下的文件移动到/usr/include/eigen3 完成更新
仍然报相同错误
sudo cp -r /usr/include/eigen3/Eigen /usr/local/include
仍然报相同错误
将 ~/Downloads/eigen-3.3.7/install/share/eigen3/cmake下的四个文件拷贝到/usr/lib/cmake/eigen3下面
