Link MySQL Librarys in CMake - c++

Question

I'm starting to learn how to use CMake, but I have had several problems with the linking libraries. Now my problem is with MySQL (C). As there is by default the FindMySQL.cmake I included one that I found, however, it does not solve because my libraries are in separate folders within the project.
My project structure:
/
/ CMakeLists.txt
/include
/include/mysql (...)
/lib (libmysql.lib, mysqlclient.lib, libmysql.dll)
/src (main.cpp)
/src/login (login.cpp, login.h)
/build (Build Directory of CMake)
Sorry for the lack of organization, but is that a long time since I have this problem and I'm using "angry."
My current CMakeLists:

But if I use that, return this error:

Thanks, Bruno Alano.

CMAKE_LIBRARY_PATH is where CMake puts the libraries it builds, not where it looks for existing libraries.
Try adding link_directories("${PROJECT_SOURCE_DIR}/lib") before add_executable.
Then do make VERBOSE=1 to see what compiler options are being passed--hopefully one of them will be the -L (library search path) you just added.
