我是新來的CMake，但我能夠爲我的C++項目設置CMakeLists.txt文件，它類似於this setup，順便說一下。我需要使用UnitTest ++進行單元測試，但出於某種原因鏈接單元測試可執行文件失敗。這裏是shell輸出：cmake - UnitTest ++鏈接單元測試二進制文件失敗

這是我的根的CMakeLists.txt文件：
jorge [~/coders/desarrollo/santotomasdeaquino] ~> cat CMakeLists.txt
cmake_minimum_required(VERSION 2.8)
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/CMakeModules/")
# project name
project(tomas-aquino)
# In this project, Boost is gonna be use
find_package(Boost 1.48.0 REQUIRED COMPONENTS filesystem)
include_directories(${Boost_INCLUDE_DIRS})
set(LIBS ${Boost_LIBRARIES})
message(STATUS "Librerias: ${LIBS}")
include_directories(include)
include_directories(tests)
enable_testing()
add_subdirectory(src)
add_subdirectory(tests)
jorge [~/coders/desarrollo/santotomasdeaquino] ~>
，這是關係到我的可執行的單元測試的二進制文件我的CMakeLists.txt文件：
jorge [~/coders/desarrollo/santotomasdeaquino] ~> cat tests/CMakeLists.txt
enable_testing()
find_package(UnitTest++ REQUIRED)
include_directories(${UNITTEST++_INCLUDE_DIRS})
set(LIBS ${LIBS} ${UNITTEST_LIBRARIES} ResourceManager)
add_executable(test_resourcemanager test_resourcemanager.cpp)
message(STATUS "Librerias: ${LIBS}")
target_link_libraries(test_resourcemanager ${LIBS})
add_test(test_resourcemanager ${CMAKE_CURRENT_BINARY_DIR}/test_resourcemanager)
get_property(dirs DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} PROPERTY INCLUDE_DIRECTORIES)
foreach(dir ${dirs})
message(STATUS "dir='${dir}'")
endforeach()

這裏是與構建我的項目的庫有關的最後一個CMakeLists.txt文件：
jorge [~/coders/desarrollo/santotomasdeaquino] ~> cat src/CMakeLists.txt
include_directories(./tomasaquino)
add_library(ResourceManager ./tomasaquino/ResourceManager.cpp)
jorge [~/coders/desarrollo/santotomasdeaquino] ~>
我在做什麼錯？
