C++ Cassandra build error - c++

Question

Hello i have a problem with building my code in c++.
I have installed cassandra on my Mac OS and all libraries that i need from datastax.
But when i build my test project i always get
Undefined symbols for architecture x86_64:
"_cass_cluster_free", referenced from:
_main in main.cpp.o
"_cass_cluster_new", referenced from:
_main in main.cpp.o
"_cass_cluster_set_contact_points", referenced from:
_main in main.cpp.o
"_cass_error_desc", referenced from:
_main in main.cpp.o
"_cass_future_error_code", referenced from:
_main in main.cpp.o
"_cass_future_free", referenced from:

"_cass_session_connect", referenced from:

"_cass_session_free", referenced from:
_main in main.cpp.o
"_cass_session_new", referenced from:
_main in main.cpp.o
ld: symbol(s) not found for architecture x86_64
I know that i'm missing something in my CMakelist but i dont know exactly what
Here is my test code:
#include <cassandra.h>
#include <cstdio>
int main() {
/* Setup and connect to cluster */
CassCluster* cluster = cass_cluster_new();
CassSession* session = cass_session_new();
/* Add contact points */
cass_cluster_set_contact_points(cluster, "127.0.0.1");
/* Provide the cluster object as configuration to connect the session */
CassFuture* connect_future = cass_session_connect(session, cluster);
/* This operation will block until the result is ready */
CassError rc = cass_future_error_code(connect_future);
printf("Connect result: %s\n", cass_error_desc(rc));
/* Run queries... */
cass_future_free(connect_future);
cass_session_free(session);
cass_cluster_free(cluster);
return 0;
}

On MacOS the default installation directory is /usr/local with header files being installed in include and libraries being installed in lib. To ensure that the driver is installed properly you can compile your example code via clang++
clang++ <source_file_name> -o <executable_output> -lcassandra
To correct your issue with the CMake (CMakelists.txt) configuration you need to make sure that you use target_link_libraries(<target> cassandra) in order for your application to link against the driver library installed on your system.
