Add static library czmq to C project (CMake)

Question

I am writing a project in C using the ZeroMQ library. I need to use a static library. CMakeLists.txt:

cmake_minimum_required(VERSION 3.17)

project(client C CXX)

set(CMAKE_C_STANDARD 99)

find_library(czmq_location NAMES libczmq.a)
message(STATUS ${czmq_location})

add_library(czmq STATIC IMPORTED)
set_target_properties(czmq PROPERTIES IMPORTED_LOCATION ${czmq_location})

add_executable(client client.c ft_lib_c/clib.c ft_lib_c/clib.h ft_lib_c/itoa.c ft_lib_c/itoa.h)

target_link_libraries(client czmq  )

However, when building, I get a lot of errors -_-:

CMakeFiles/client.dir/client.c.o: In function `main':
/home/neleps/MMS_radar_projects/master/client/client.c:18: undefined reference to `zmq_ctx_new'
/home/neleps/MMS_radar_projects/master/client/client.c:20: undefined reference to `zmq_socket'
/home/neleps/MMS_radar_projects/master/client/client.c:22: undefined reference to `zmq_connect'
....

That is, the functions from the library are not visible . What am I doing wrong?

Thank you in advance for your help :)

This worked well for me:

target_link_libraries(server PRIVATE czmq zmq)

The complete CMakeLists.txt:

cmake_minimum_required(VERSION 3.15)
set(CMAKE_C_STANDARD 11)
project(client C)

find_library(ZeroMQ czmq REQUIRED)

add_executable(client)
target_link_libraries(client PRIVATE czmq zmq)

target_include_directories(client PRIVATE include)
target_sources(client PRIVATE 
    src/client.c)
