c-与cmake,icc和pthreads链接(Linux)

我正在尝试使用Intel C编译器,CMake和std :: threads支持来编译一个简单的测试项目.

如果我做 ：

icpc -std=c++11 -lpthread source/main.cpp

然后,构建和程序运行正常.

但是使用CMake我得到一个错误：

CMake Error at CMakeLists.txt:21 (TARGET_LINK_LIBRARIES):
  Cannot specify link libraries for target "test" which is not built by
  this project.

CMakeLists.txt是：

project(test)
set (CMAKE_CXX_FLAGS "-std=c++11")
set(SOURCE_LIST "source/main.cpp")
TARGET_LINK_LIBRARIES(${PROJECT_NAME} pthread)
add_executable (${PROJECT_NAME} ${SOURCE_LIST})

我正在由icc(compilervars.sh)提供的脚本设置的环境中构建,并且使用-DCMAKE_C_COMPILER = icc -DCMAKE_CXX_COMPILER = icpc选项调用CMake.如果我不使用线程,它可以工作.

我使用CMake有什么问题？

谢谢！

解决方法:

回顾target_link_libraries的文档,必须在使用目标之前声明该目标：

The named <target> must have been created in the current directory by a command such as 07001 or 07002.

BTW如this answer中所述,您不应显式设置CMAKE_CXX_FLAGS,而应该设置CMAKE_CXX_STANDARD和相关变量：

project(test)

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_EXTENSIONS OFF)

set(SOURCE_LIST "source/main.cpp")

add_executable(${PROJECT_NAME} ${SOURCE_LIST})

target_link_libraries(${PROJECT_NAME} pthread)
