问题：

解决办法就是：查看你的cmake .. 后上面的一些错误提示和警告，基本上是CMakeLists.txt中的一些库是否链接好了

例如我当时的CMakeLists.txt：

set(CMAKE_CXX_FLAGS"-std=c++11")
cmake_minimum_required(VERSION 3.10)

project(stereoVision)
find_package(OpenCV REQUIRED)

#添加头文件
include_directories(${OpenCV_INCLUDE_DIRS})

find_package(Pangolin REQUIRED)
include_directories(${Pangolin_INCLUDE_DIRS})

# 链接OpenCV库
add_executable(stereoVision stereoVision.cpp)
target_link_libraries(stereoVision ${OpenCV_LIBS} ${Pangolin_LIBRARIES})
