Static linking ActiveMQ-cpp

I am creating a c++ project where I want it to run in standalone mode without any dependencies since it will be deployed on multiple servers.

This is my CMAKELISTS file :

project(CMS-test)
cmake_minimum_required(VERSION 2.6)

add_executable(main main.cpp)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

INCLUDE_DIRECTORIES(/usr/local/apr/include/apr-1)
INCLUDE_DIRECTORIES(/usr/local/include/activemq-cpp-3.9.4)

target_link_libraries(main ${CMAKE_SOURCE_DIR}/libapr-1.a)
target_link_libraries(main ${CMAKE_SOURCE_DIR}/libactivemq-cpp.a)

but the error I'm getting after make main during linking is

and more..

Any advice ?
