PCL make error: Undefined symbols for architecture x86_64 @pcl

No error using cmake ..

Error occurs when make as following: 

Scanning dependencies of target environment
[ 25%] Building CXX object CMakeFiles/environment.dir/src/environment.cpp.o

The cmakelists.txt are

cmake_minimum_required(VERSION 2.8 FATAL_ERROR)    
add_definitions(-std=c++11)    
set(CXX_FLAGS "-Wall")
set(CMAKE_CXX_FLAGS, "${CXX_FLAGS}")    
project(playback)    
find_package(PCL 1.2 REQUIRED COMPONENTS common io)    
include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})
list(REMOVE_ITEM PCL_LIBRARIES "vtkproj4")
add_executable (environment src/environment.cpp src/render/render.cpp src/processPointClouds.cpp)
target_link_libraries (environment ${PCL_LIBRARIES})

OS mac catarina PCL 1.9 xcode

The problem should be related to cmakelists.txt such as library links, but I have no any ideas to locate and fix it.

Solved by linking libraries:

find_package(PCL 1.3 REQUIRED COMPONENT common io VISUALIZATION)

target_link_libraries (environment ${PCL_LIBRARIES} ${PCL_COMMON_LIBRARIES} ${PCL_IO_LIBRARIES} ${PCL_VISUALIZATION_LIBRARIES})
