目前我把下载的mysql/Connector 下载后放在了project内 但是报错信息如下
报错信息如下

文件引用情况如下:
在网上搜索有很多连接的方法 目前还是有点晕 望指教
这儿有一个CMake module用来找mysql connector
https://github.com/windoze/fibio/blob/master/cmake/Modules/FindMySQLConnectorCPP.cmake
然后你就可以写find_package(MySQLConnectorCPP)
了
他不是都提示你用""而不是<>了么
另外, 你貌似用了CMake, 那你把库的路径加到include路径里面去. 比如说deps路径下有mysql文件夹, 我代码里面要写#include <mysql/mysql.h>
, 那么在cmake里面写INCLUDE_DIRECTORIES(deps)
