OpenImageIOをCMakeにリンクできません

Question

私はOpenImageIOをCMakeを使って実行可能ファイルにリンクしようとしていますが、ビルドのリンク段階ではエラーが発生し続けます。誰でもCMakeLists.txtを正しく設定してライブラリがリンクするように知っていますか？

CMakeLists.txt

cmake_minimum_required(VERSION 2.8.4) 

project(VolumeFX) 

add_compile_options(-std=c++11) 

if(${CMAKE_SYSTEM_NAME} MATCHES "Darwin") 
    include_directories("/usr/local/include") 
    find_library(OIIO "OpenImageIO" "/usr/local/lib") 
elseif(${CMAKE_SYSTEM_NAME} MATCHES "Linux") 
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fopenmp") 
    include_directories("/group/dpa/include") 
    find_library(OIIO "OpenImageIO") 
endif(${CMAKE_SYSTEM_NAME} MATCHES "Darwin") 

set(SOURCE_FILES 
     main.cpp 
     Vector.h 
     Camera.cpp 
     Camera.h 
     FloatVolume.h 
     SphereVolume.cpp 
     SphereVolume.h 
     ClampMin.cpp 
     ClampMin.h 
     Renderer.cpp 
     Renderer.h 
     Image.cpp 
     Image.h 
     OIIOFiles.cpp 
     OIIOFiles.h) 

add_executable(${PROJECT_NAME} ${SOURCE_FILES}) 

if(${CMAKE_SYSTEM_NAME} MATCHES "Darwin") 
    target_link_libraries(${PROJECT_NAME} ${OIIO}) 
elseif(${CMAKE_SYSTEM_NAME} MATCHES "Linux") 
    target_link_libraries(${PROJECT_NAME} ${OIIO}) 
endif(${CMAKE_SYSTEM_NAME} MATCHES "Darwin") 

ここでメイクファイルを実行しているからの出力は、あなたがOpenImageIOライブラリを参照するために間違った変数名を使用し...
