我正在构建一个使用Rcpp的R包，需要与mongodb c ++驱动程序一起使用。我正在使用Windows，并通过柯南软件包管理器安装了mongo c驱动程序（版本1.11.0）和mongo cxx驱动程序（版本3.3.0）。使用柯南指导，我构建驱动程序，并将生成的conanbuildinfo.gcc文件的内容用于我的Makevars文件中的PKG_CXXFLAGS标志。

当我在Rstuido中的Cpp文件中编码时，它会识别mongo标头，并为我键入时提供自动完成的建议。当我尝试构建软件包时，出现错误：

这是由以下代码引起的：
mongocxx::instance inst{};
在网上浏览并阅读了SO帖子后，我认为编译器未正确链接到我需要使用的标头。我不知道如何解决此问题，将不胜感激。用于构建我的程序包的编译器是gcc 4.9.3。
