克利翁和 CMake。如何添加库（*.so）

我正在尝试在 Clion IDE 中编写（c/c++）代码。我需要在我的项目中添加一些共享库。此时，我只想运行主函数，它将添加我的外部库 libAPIenergy.so 具有的所有函数。我尝试了该论坛的一些解决方案，但没有一个有帮助。

下面我将提出错误最少的解决方案。

在主要功能中我包括

#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

Makefile:118: polecenia dla obiektu 'TestProject' nie powiodły się
make: *** [TestProject] Błąd 2

我还添加到系统路径LD_LIBRARY_PATH与我的共享库的目录

export LD_LIBRARY_PATH=$HOME/Lib/Linux/x86

。：：编辑：：。 1

My CMake下班后建议

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。我部署了APIenergy.h文件到项目的主目录。

.::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)

Error

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)

简单地写下我尝试过的午餐

#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;
}

编译器错误

Use add_library如果您要从源文件创建自己的库。

Use target_link_libraries如果您指定您的目标需要链接到其他人的库。
