Error running example

Compiling in Linux gives me error.
I am supposed to use below CMakeLists.txt file
cmake_minimum_required(VERSION 3.0)
project(clickhouse-example)
set(CMAKE_CXX_STANDARD 17)
add_executable(${PROJECT_NAME} "clickhouse.cpp")
target_link_libraries(${PROJECT_NAME} /usr/local/lib/libclickhouse-cpp-lib.so)
I have libclickhouse-cpp-lib.a at usr/local/lib and hence I modified above file as..
target_link_libraries(${PROJECT_NAME} /usr/local/lib/libclickhouse-cpp-lib.a)
Below is the error, I get
/usr/bin/ld: /usr/local/lib/libclickhouse-cpp-lib.a(types.cpp.o): in function clickhouse::Type::GetTypeUniqueId() const': types.cpp:(.text+0x3493): undefined reference to CityHash64WithSeed(char const*, unsigned long, unsigned long)'

I built the library using the steps provided on github
g++ (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0
cmake version 3.16.3
Please help.
Can you upload the CMakeLists.txt and simple code ? @Abhi4356-S
Hi
I resolved the above issue. I am trying to use this library in my project to check if click house fits our project. I am using the libclickhouse-cpp-lib.so file to link to our code.
I am able to compile it using g++ without any errors
g++ test1.cc -o test -L/home/Proj/lib -Wl,-R/home/Proj/lib -lclickhouse-cpp-lib
but with CMakeLists.txt file it is giving me below error
/usr/bin/ld: src/unit_test/metrics1/CMakeFiles/ut_metrics1.dir/test1.cc.o: in function main::{lambda(clickhouse::Block const&)#1}::operator()(clickhouse::Block const&) const': /home/user1/Proj/builds/trp/Build/../src/unit_test/metrics1/test1.cc:41: undefined reference to clickhouse::ColumnString::At(unsigned long) const'

collect2: error: ld returned 1 exit status
My CMakeLists.txt file:
set(outfileNameNoExt test)
set(projectName ut_metrics1)
set(SRCS test1.cc)
add_executable(${projectName} ${SRCS})
TARGET_PROPS(${projectName} ${outfileNameNoExt})
LINK_DIRS(${projectName})
if (MSVC)
LINK_AGAINST(${projectName} clickhouse-cpp-lib
)
elseif(LINUX)
set (libList clickhouse-cpp-lib)
LINK_AGAINST(${projectName} ${libList})
endif()
Please help
please use link_directories and target_link_libraries
