It's where mysqlclient.so located

[dbn@hecs-137331 mysql]$ pwd
/usr/lib64/mysql
[dbn@hecs-137331 mysql]$ ls
INFO_BIN  libmysqlclient.so  libmysqlclient.so.21       plugin
INFO_SRC  libmysqlClient.so  libmysqlclient.so.21.1.26

And this is how my CMakeLists.txt include the lib

target_include_directories(main PUBLIC "usr/lib64/mysql")
include_directories("usr/lib64/mysql")                               
target_link_libraries(main mysqlclient)

This is the error message

[dbn@hecs-137331 build]$ make
[ 14%] Built target zlog
[ 23%] Built target buffer
[ 47%] Built target http
[ 61%] Built target pool

I just install mysql by 'sudo yum install mysql' so There is no file named 'mysqlConfig.cmake' and i dont use find_package

Currently, link_directories("usr/lib64/mysql") target_link_libraries(main mysqlclient) link_directories("usr/lib64/mysql") all of above cannot find the libmysqlclient.so and show the message /usr/bin/ld: cannot find -lmysqlclient

And I also Tried to copy the lib to the /usr/bindirctory. It doesn't work too.

I'm pretty sure you meant to use link_directories somewhere in there. And that path is an absolute path, so it should be prefixed with a slash. Ex. link_directories("/usr/lib64/mysql").

Also, I don't see the point in your *_include_directories command calls, since from your ls output, it doesn't look like there is anything in there that you'd want to #include.

Note: I'm not sure if it's a great idea to be hardcoding machine-specific paths into your CMake project config.
