C++ CMake-创建静态库

我的项目中有两个名为

Test4

的文件：

Structure.h

Structure.c

我想创建一个静态库，它可以由希望使用这些文件的其他项目加载。这是我当前的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。什么也没发生。我做错什么了吗

我正在使用CLion IDE。

添加库行应该是您所需要的全部。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;
}

主要条款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;
}

下面是运行它的输出：

我也有同样的问题。我错过的是创建构建文件的位置

---

CLion在

cmake build-*

目录下创建库或可执行表。如果

Build、Execution、Deployment>CMake>Configuration

为

Debug

，则在使用命令CMake.后，会在

CMake Build Debug

下创建库文件（

.a

），然后Makefile将具有类似于设置默认\u目标的选项，撤销它，然后在r目录中得到一个.a文件。

这解决了问题吗？我想知道更多，因为我有一个类似的问题。我看不出这和OP的代码有什么不同。
