C++ 未能链接UnitTest++；

我想在项目中使用，但在编译时出错：

CMakeFiles/BNN.dir/main.cpp.o:-1: In function `main':
BNN/main.cpp:-1: error: undefined reference to `UnitTest::RunAllTests()'
:-1: error: collect2: error: ld returned 1 exit status

我在网上搜索答案，并尝试了几件我现在拥有的东西：

project(BNN)
cmake_minimum_required(VERSION 2.8)

file(GLOB SRC "*.cpp" "src/*.h" "src/*.cpp")
file(GLOB DATA_FILE "*.md")

find_package(UnitTest++ REQUIRED)
include_directories(${UnitTest++_INCLUDE_DIRS})
set(LIBS ${LIBS} ${UnitTest++_LIBRARY})

add_executable(${PROJECT_NAME} ${SRC} ${DATA_FILE})
target_link_libraries(${PROJECT_NAME} ${LIBS})

我按照官方指南建立图书馆：

cd path/to/unittest-cpp/builds
cmake -G "<Choose a valid generator>" ../
cmake --build ./
sudo cmake --build ./ --target install

cd路径/to/unittest cpp/builds
cmake-G“/
cmake——构建/
sudo cmake--构建/--目标安装

我的操作系统是ArchLinux

我必须做些什么才能用cmake编译它？

我通过将我的cmake文件更改为：

project(BNN)
cmake_minimum_required(VERSION 2.8)

include_directories(src)

file(GLOB SOURCES "*.cpp" "src/*.h" "src/*.cpp" "tests/*.cpp")
file(GLOB DATA_FILE "*.md")

add_executable(${PROJECT_NAME} ${SOURCES} ${DATA_FILE})
target_link_libraries(${PROJECT_NAME} ${CMAKE_SOURCE_DIR}/../unittest-cpp/builds/libUnitTest++.a)

---

我已将我的cmake文件更改为：

project(BNN)
cmake_minimum_required(VERSION 2.8)

include_directories(src)

file(GLOB SOURCES "*.cpp" "src/*.h" "src/*.cpp" "tests/*.cpp")
file(GLOB DATA_FILE "*.md")

add_executable(${PROJECT_NAME} ${SOURCES} ${DATA_FILE})
target_link_libraries(${PROJECT_NAME} ${CMAKE_SOURCE_DIR}/../unittest-cpp/builds/libUnitTest++.a)
