关于编译PCL1.71

最近在编译PCL1.71时总会出现错误，

编译的时候就出现无法生成pcl_io_debug.lib
由于无法生成pcl_io_debug.lib,。

借鉴PCL中国的经验：

（1）：把ioincludepcliopng_io.h文件报错地方”template <“的前四行注释掉，重新编译io模块
//    PCL_DEPRECATED (template <typename T> void savePNGFile (const std::string& file_name, const pcl::PointCloud<T>& cloud),
//    "pcl::io::savePNGFile<typename T> (file_name, cloud) is deprecated, please use a new generic "
//    "function pcl::io::savePNGFile (file_name, cloud, field_name) with "rgb" as the field name."
//    );

（2）：不用去掉，改成
template <typename T> PCL_DEPRECATED ( void savePNGFile (const std::string& file_name, const pcl::PointCloud<T>& cloud),
    "pcl::io::savePNGFile<typename T> (file_name, cloud) is deprecated, please use a new generic "
    "function pcl::io::savePNGFile (file_name, cloud, field_name) with "rgb" as the field name."
    );
common/include/pcl/ros/conversions.h 同样改法。
