[UE4]windows和android调用第三方C++库(静态库lib、动态库dll)

C++调用动静态链接库Dynamic Link Library（dll）

再给一个Android版本添加静态库的例子，参考Photon SDK（在“工程.Build.cs”中添加），其实linux、windows也都是这么添加的，区别就是引用的文件不一样，windows是dll和lib，linux是.so和.a（linux上的so和a文件和android上的so和a文件是两码事，android上的so和a必须通过NDK编译获得）：

private string PhotonPath
{
    get { return Path.GetFullPath(Path.Combine(ModulePath, "..", "Photon")); }
}
//
if ( Target.Platform == UnrealTargetPlatform.Android)
{
    // Set _EG_WINDOWS_PLATFORM for Windows, _EG_IPHONE_PLATFORM for iOS and _EG_IMAC_PLATFORM for OS X
    Definitions.Add("_EG_ANDROID_PLATFORM");
    //
    PublicAdditionalLibraries.Add(Path.Combine(PhotonPath, "lib", "Android", "libcommon-cpp-static_debug_android_armeabi_no-rtti.a"));
    PublicAdditionalLibraries.Add(Path.Combine(PhotonPath, "lib", "Android", "libphoton-cpp-static_debug_android_armeabi_no-rtti.a"));
    PublicAdditionalLibraries.Add(Path.Combine(PhotonPath, "lib", "Android", "libloadbalancing-cpp-static_debug_android_armeabi_no-rtti.a"));
}
