c++ - 如何使用 CMake 正确链接外部库？

Question

我正在尝试使用 Chilkat C++ 库进行密码分配，但我似乎无法正确链接该库。截至目前，编译器无法找到头文件 CkRsa.h。我花了几个小时在互联网上搜索解决方案，但无济于事。到目前为止，这是我所拥有的(这都是在 Mac OS X 环境中进行的):

lib 文件安装在/users/Adam/Desktop/chilkat/libDyn 中，头文件在/users/Adam/Desktop/chilkat/include 中这是我的 CMakeLists.txt

cmake_minimum_required(VERSION 3.6)
project(SocketEncryption)

set(CMAKE_CXX_STANDARD 11)

set(SOURCE_FILES main.cpp)

add_library(chilkat STATIC IMPORTED)
set_property(
        TARGET chilkat
        PROPERTY
        IMPORTED_LOCATION "/users/Adam/Desktop/chilkat/libDyn/libchilkat_x86_64.dylib"
        INTERFACE_INCLUDE_DIRECTORIES "/users/Adam/Desktop/chilkat/include"
)
add_executable(SocketEncryption ${SOURCE_FILES})

target_link_libraries(SocketEncryption chilkat)

这是我的 main.cpp

#include <iostream>
#include <CkRsa.h>
//#include <CkPrivateKey.h>
//#include <CkSocket.h>

int main() {
    CkRsa alice;
    CkRsa bob;

    // Key Generation
    bool success = alice.GenerateKey(1024);
    const char *alicePublicKey = alice.exportPublicKey();
    const char *alicePrivateKey = alice.exportPrivateKey();
    const char *aliceMessage = "Hi, Bob. How are you?";

    // Encryption Step
    std::cout << "Encryption started." << std::endl;
    CkRsa rsaEncryptor;
    rsaEncryptor.put_EncodingMode("hex");
    success = rsaEncryptor.ImportPublicKey(alicePublicKey);
    bool usePrivateKey = false;
    const char * ciphertext = rsaEncryptor.encryptStringENC(aliceMessage, success);
    std::cout << ciphertext << std::endl;


    return 0;
}

像这样更改您的代码(引用):

include_directories("/users/Adam/Desktop/chilkat/include")
link_directories("/users/Adam/Desktop/chilkat/libDyn")
