编译过程报错

在Ubuntu 16上按照您的安装步骤进行安装，在make时报错：

/home/xxxxxx/CloudViewer/src/FileIO.h:46:5: error: could not convert ‘{{"ply", "Stanford Polygon File Format (.ply)"}, {"pcd", "PCL Point Cloud Data (.pcd)"}, {"obj", "Alias Wavefront Object (.obj)"}, {"stl", "STL File Format (.stl)"}, {"vtk", "Visualization Tookit Format (.vtk)"}, {"", "All Files (.)"}}’ from ‘’ to ‘std::map<std::__cxx11::basic_string, std::__cxx11::basic_string >’
