c 11 – Clion&CMake.如何添加库(* .so)

我尝试在Clion IDE中编写代码(c / c).我需要在项目中添加一些共享库.在这一刻,我想只运行程序(只有主要功能),它将能够添加我的外部库libAPIenergy.so的任何功能.我从这个论坛尝试了一些解决方案,但任何人都没有帮助.

下面我将介绍给出最少错误的解决方案.

在主要功能我包括

#include "APIenergy.h"

CMake文件

cmake_minimum_required(VERSION 3.3)
project(TestProject)
add_library( libAPIenergy SHARED IMPORTED )
link_directories (/home/I/Lib/Linux/x86)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -lAPIenergy ")
set(SOURCE_FILES main.cpp APIenergy.h)
add_executable(TestProject ${SOURCE_FILES})

和错误：

/home/I/clion-1.2/bin/cmake/bin/cmake --build /home/I/.CLion12/system/cmake/generated/9faec492/9faec492/Debug --target TestProject -- -j 8

make: *** [TestProject] B??d 2

我还使用我的共享库添加到系统PATH LD_LIBRARY_PATH direcytory

export LD_LIBRARY_PATH=$HOME/Lib/Linux/x86

.：：编辑：：. 1

我的CMake在你的消化之后

cmake_minimum_required(VERSION 3.3)
project(TestProject)
add_library(libAPIenergy SHARED IMPORTED)
SET_PROPERTY(TARGET libAPIenergy PROPERTY IMPORTED_LOCATION /home/I/x86/libAPIenergy.so)
target_link_libraries(TestProject libAPIEnergy)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES main.cpp APIenergy.h)
add_executable(TestProject ${SOURCE_FILES})

来自CMake的错误

Error:Cannot specify link libraries for target "TestProject" which is not built by this project.

还有一件重要的事情.我用项目将APIenergy.h文件部署到主目录.

.::编辑2 ::.

cmake_minimum_required(VERSION 3.3)
project(TestProject)
add_library(libAPIenergy SHARED IMPORTED)

target_link_libraries(TestProject libAPIenergy)
SET_PROPERTY(TARGET libAPIenergy PROPERTY IMPORTED_LOCATION /home/I/lib/x86/libAPIenergy.so)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES main.cpp APIenergy.h)

add_executable(TestProject ${SOURCE_FILES})
target_link_libraries(TestProject libAPIenergy)

错误

Error:Cannot specify link libraries for target "TestProject" which is not built by this project.

.::编辑3 ::.

现在CMake文件没有错误

cmake_minimum_required(VERSION 3.3)
project(TestProject)
add_library(libAPIenergy SHARED IMPORTED)

SET_PROPERTY(TARGET libAPIenergy PROPERTY IMPORTED_LOCATION /home/I/lib/x86/libAPIenergy.so)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES main.cpp APIenergy.h)

add_executable(TestProject ${SOURCE_FILES})
target_link_libraries(TestProject libAPIenergy)

简单地说我尝试过午餐的代码

#include <iostream>
#include "APIenergy.h" // include without error this mean without underlined

using namespace std;

int main() {

    int ret = APIenergyInitialize(5); // IDE suggestions name function so is looks good

    cout << "Hello,World!" << endl;
    return 0;
}

编译错误
