使用Cmake编译QtGstreamer时出错，Mingw32编译器附带QT5.12.3

Question

我试图编译QT的GStreamer包装器，所以我使用QT5.12.3和Mingw32 7.3.0下载了两个iam包

1. gstreamer-1.0-devel-mingw-x86-1.16.0.msi
2. gstreamer-1.0-mingw-x86-1.16.0.msi

然后我安装了它们，并将bin文件夹添加到系统环境中，这样Cmake就可以在编译GStreamer时识别QtGstreamer所需的依赖项，我下载了最后一个版本的QtGStreamer 1.2.0并使用Cmake生成文件，我链接了所有的依赖项，即QT、Boost和GStreamer。

当我进入mingw32 32-make的步骤时，在17%上出现了错误，即

我犯了什么错？

我不知道是否还需要什么来纠正我的错误，请告诉我你是否需要添加什么

更新

当我配置Cmake选项时，我没有添加qt5declarative Cmake，而是空的，在对这个部分进行搜索之后，我发现Qt5.6中不再支持这个部分，我不确定这个问题是否与这个部分有关，但总的来说，这是我迄今为止所做的所有工作。

您应该尝试使用GStreamer1.14.4
