我目前尝试将外部动态链接库（dll）添加到我的 cmake 项目中。我有 .dll 和 .lib 文件。我花了很多时间自己寻找答案，但我没有找到解决方案。包含有效，但是当我尝试编译最小解决方案时总是会出现链接错误。CMAKE 在配置和生成并找到库时不会抛出任何错误。我希望有人以前遇到过问题并认识到我的错误

我还构建了自己的查找模块，看起来像这样

find_path(LLT_INCLUDE_DIR InterfaceLLT_2.h HINTS ${LLT_DIR})

find_library(LLT_LIBRARY NAMES LLT HINTS ${LLT_DIR} )

set(LLT_LIBRARIES ${LLT_LIBRARY} )

set(LLT_INCLUDE_DIRS ${LLT_INCLUDE_DIR} )

include(FindPackageHandleStandardArgs)

# handle the QUIETLY and REQUIRED arguments and set LIBXML2_FOUND to TRUE

# if all listed variables are TRUE

find_package_handle_standard_args(LLT  DEFAULT_MSG LLT_LIBRARY LLT_INCLUDE_DIR)

mark_as_advanced(LLT_INCLUDE_DIR LLT_LIBRARY )

对应的 CMakeLists.txt 看起来像这样

PROJECT(TestProg)

cmake_minimum_required(VERSION 2.8)

FIND_PACKAGE(LLT REQUIRED)

INCLUDE_DIRECTORIES(${LLT_INCLUDE_DIR})

SET(TestProg_SOURCES

main.cpp

)

SET(TestProg_HEADERS

)

add_executable(TestProg ${TestProg_SOURCES} ${TestProg_HEADERS})

target_link_libraries(TestProg ${LLT_LIBRARIES} )

这是CMAKE输出

这是代码片段。我真的不知道您对链接命令的含义是什么，还是我忘记了代码中的某些内容？

#include <iostream>
#include "InterfaceLLT_2.h"
using namespace std;

int main()
{

    bool bLoadError;

    CInterfaceLLT* m_pLLT;

     m_pLLT = new CInterfaceLLT("LLT.dll", &bLoadError);

     cout << "Hello World!" << endl;



    return 0;
}
