CMake - 创建一个静态库

Question

我的项目中有两个文件名为 Test4 ：

Structure.h Structure.c

我想创建一个静态库，可以由其他想要使用这些文件的项目加载。这是我目前的 CMake 文件：

 cmake_minimum_required(VERSION 3.6)
project(Test4)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

set(SOURCE_FILES Structure.c Structure.h)
add_library(Test4 STATIC ${SOURCE_FILES})

当我使用该 CMake 文件构建时，不会生成静态库。什么都没发生。难道我做错了什么？

我正在使用 CLion IDE。

add_library 行应该是您所需要的。请参阅我刚刚编写的示例代码，以测试创建一个然后使用它（在 Ubuntu 16.04 上）：

结构.h：

 int sum( int a, int b );

结构.c：

 int sum( int a, int b ) {
    return a + b;
}

主要.c：

 #include <stdio.h>
#include "Structure.h"

int main() {
    int a = 5;
    int b = 8;
    int c = sum( a, b );

    printf( "sum of %d and %d is %d\n", a, b, c );

    return 0;
}

CMakeLists.txt：

 # CMake instructions to make the static lib

ADD_LIBRARY( MyStaticLib STATIC
             Structure.c )

# CMake instructions to test using the static lib

SET( APP_EXE StaticTest )

ADD_EXECUTABLE( ${APP_EXE}
                Main.c )

TARGET_LINK_LIBRARIES( ${APP_EXE}
                       MyStaticLib )

然后这是运行它的输出：
