CMake的 - 创建一个静态库

问题描述：

我有我的项目的两个文件名为Test4：CMake的 - 创建一个静态库

Structure.h Structure.c

我想创建一个可以谁想要使用这些文件的其他项目加载的静态库。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，没有生成静态库。什么都没发生。难道我做错了什么？

我正在使用CLion IDE。

add_library行应该是你所需要的。看到这个例子的代码，我只是写来测试一个创建，然后使用它（在Ubuntu 16.04）：

Structure.h：

int sum(int a, int b);

Structure.c：

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

主。 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; 
}

的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)

然后在这里是运行它的输出：

CMakeLists.txt Main.c Structure.c Structure.h

我有同样的问题。我错过了创建文件的位置。

CLion在cmake-build-*目录下制作库或可执行文件。如果Build, Execution, Deployment > CMake > Configuration是Debug，则在cmake-build-debug下创建lib文件（.a）。
