如何使用 Cmake 为 SimuroSot 模拟器构建（从 DevCpp 转换）Win32 DLL

Question

我需要准备 SimuroSot（机器人的足球模拟器）策略（该程序读取的 dll）。 如果我可以在 CLion 中编写它会很棒，但我没有 CMake 的经验。

我拥有的唯一工作版本是 DevCpp 项目。怎么转成Cmake？

项目包含：

• 具有 3 个导出函数和一些结构的 Strategy.h。
• 带有 DllMain 函数的 Strategy.cpp

它构建文件：

• Team2.dll
• libTeam2.a
• libTeam2.def

来自 Strategy.dev 的 IMO 重要选项：

Compiler=-D__GNUWIN32__ -W -DWIN32 -DNDEBUG -D_WINDOWS -D_MBCS -D_USRDLL -DSTRATEGY_EXPORTS_@@_
CppCompiler=-D__GNUWIN32__ -W -DWIN32 -DNDEBUG -D_WINDOWS -D_MBCS -D_USRDLL -DSTRATEGY_EXPORTS_@@_
Linker=-lkernel32 -luser32 -lgdi32 -lwinspool -lcomdlg32 -ladvapi32 -lshell32 -lole32 -loleaut32 -luuid -lodbc32 -lodbccp32_@@_

那是我目前的CMake，只创建了Team2.dll，不执行导出的函数（可见）：

cmake_minimum_required(VERSION 3.6)
project(SimuroSotTest)
set(CMAKE_CXX_STANDARD 98)

set(SOURCE_FILES
        library.cpp
        library.h
        )

add_library(Team2 MODULE ${SOURCE_FILES})
set_target_properties(Team2 PROPERTIES PREFIX "")
target_compile_options(Team2 PRIVATE -D__GNUWIN32__ -W -DWIN32 -DNDEBUG -D_WINDOWS -D_MBCS -D_USRDLL -DSTRATEGY_EXPORTS)
install(TARGETS Team2 DESTINATION /cygdrive/c/Strategy/yellow/)


# CLion does not suppot above "install" so I have to execute it
add_custom_target(
        install_all
        $(MAKE) install
        DEPENDS Team2
        COMMENT "Installing ${PROJECT_NAME}"
)

图书馆.h：

#ifndef Strategy_H
#define Strategy_H

#include <windows.h>
#include <string.h>

// The following ifdef block is the standard way of creating macros which make exporting
// from a DLL simpler. All files within this DLL are compiled with the STRATEGY_EXPORTS
// symbol defined on the command line. this symbol should not be defined on any project
// that uses this DLL. This way any other project whose source files include this file see
// STRATEGY_API functions as being imported from a DLL, wheras this DLL sees symbols
// defined with this macro as being exported.
#ifdef STRATEGY_EXPORTS
#define STRATEGY_API __declspec(dllexport)
#else
#define STRATEGY_API __declspec(dllimport)
#endif

} Environment;

/* MUST BE IMPLEMENTED */
extern "C" STRATEGY_API void Create ( Environment *env );
extern "C" STRATEGY_API void Strategy ( Environment *env );
extern "C" STRATEGY_API void Destroy ( Environment *env );

#endif // Strategy_H

库.cpp：

#include "library.h"

BOOL APIENTRY DllMain( HANDLE hModule,
DWORD  ul_reason_for_call,
        LPVOID lpReserved
)
{
switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
case DLL_THREAD_ATTACH:
case DLL_THREAD_DETACH:
case DLL_PROCESS_DETACH:
break;
}
return TRUE;
}

extern "C" STRATEGY_API void Create ( Environment *env )
{
    // allocate user data and assign to env->userData
    // eg. env->userData = ( void * ) new MyVariables ();
}

extern "C" STRATEGY_API void Destroy ( Environment *env )
{
    // free any user data created in Create ( Environment * )

    // eg. if ( env->userData != NULL ) delete ( MyVariables * ) env->userData;
}

extern "C" STRATEGY_API void Strategy ( Environment *env )
{
    env->home[0].velocityLeft = 100;
    env->home[0].velocityRight = 100;

}

问题是我将它编译为 64 位 dll。

我还将 Cygwin 更改为 MinGW，所以我的 CMakeLists.txt 现在看起来如下：

本质是-m32选项（Windows风格的路径是因为MinGW）

cmake_minimum_required(VERSION 3.6)
project(SimuroSotTest)
set(CMAKE_CXX_STANDARD 98)

set(SOURCE_FILES
        library.cpp
        library.h
        )

add_library(Team1 MODULE ${SOURCE_FILES})
set_target_properties(Team1 PROPERTIES PREFIX "" COMPILE_FLAGS "-m32" LINK_FLAGS "-m32")
target_compile_options(Team1 PRIVATE -DSTRATEGY_EXPORTS)
install(TARGETS Team1 DESTINATION C:/Strategy/blue/)


add_library(Team2 MODULE ${SOURCE_FILES})
set_target_properties(Team2 PROPERTIES PREFIX "" COMPILE_FLAGS "-m32" LINK_FLAGS "-m32")
target_compile_options(Team2 PRIVATE -DSTRATEGY_EXPORTS)
install(TARGETS Team2 DESTINATION C:/Strategy/yellow/)


# CLion does not suppot above "install" so I have to execute it
add_custom_target(
        install_all
        $(MAKE) install
        DEPENDS Team1 Team2
        COMMENT "Installing ${PROJECT_NAME}"
)
