Question

我尝试编译由GTest，OpenCV，CMake和Make组成的项目（它只是一个脚本）。层次结构是：

.
├── build
├── include
│   ├── csv_loader.h
│   ├── loader.h
│   ├── mat_reader.h
│   ├── processor.h
│   └── reader.h
├── Makefile
├── pictures
│   └── pila_original.jpg
├── sources
│   ├── CMakeLists.txt
│   ├── csv_loader.cpp
│   ├── mat_reader.cpp
│   └── processor.cpp
└── test
     ├── CMakeLists.txt
     ├── hello-test.cpp
     └── not_null_data-test.cpp

当我尝试编译整个项目时，我在test / CmakeLists.txt中遇到了这个错误：

CMakeFiles/CPOO-PROJECT-TEST.dir/not_null_data-test.cpp.o: In function `NOTNULL_flowtest_Test::TestBody()':
not_null_data-test.cpp:(.text+0x1e): undefined reference to `Processor::Processor()'
not_null_data-test.cpp:(.text+0x2d): undefined reference to `Processor::Detect()'
not_null_data-test.cpp:(.text+0xfb): undefined reference to `Processor::~Processor()'
not_null_data-test.cpp:(.text+0x145): undefined reference to `Processor::~Processor()'
collect2: error: ld returned 1 exit status

./测试/的CMakeLists.txt：

cmake_minimum_required(VERSION 2.8)
project(CPOO-PROJECT-TEST)
find_package( OpenCV 3.1.0 REQUIRED )
#eanble_testing()
find_package( GTest REQUIRED )
add_definitions(-std=c++11)


set (LIB ../release/libCPOO-PROJECT.so)
file(GLOB TEST "*.cpp")

include_directories(../include)
include_directories( ${OpenCV_INCLUDE_DIRS}
                     ${GTest_INCLUDE_DIRS})

add_executable( ${PROJECT_NAME} ${LIB} ${TEST})

target_link_libraries( ${PROJECT_NAME}
                       ${GTEST_BOTH_LIBRARIES}
                       pthread
)

我不知道如何修复链接器问题，如果需要任何其他信息，我会添加它们。

编辑1 向CMake添加标志后，我得到了这个日志：

使用cmake，gTest和OpenCV：'未定义引用'
