编译basalt时出现的报错

github/basalt/thirdparty/Pangolin/src/image/image_io_lz4.cpp:42:12: error: ‘char* strncpy(char*, const char*, size_t)’ output truncated before terminating nul copying 3 bytes from a string of the same length [-Werror=stringop-truncation]

 strncpy(header.magic,"LZ4",3);

 ~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~

cc1plus: all warnings being treated as errors
这个报错是由于在CMake的C++编译选项中添加了-Werror，即将所有警告当作错误对待，这个strncpy函数，由于是C风格的函数，拷贝字符串后面没有加’’这个结束符，但是这里其实不需要加结束符，因此在项目中全文搜索-Werror的位置，然后空一格在后面加上-Wno-error=stringop-truncation就行。

 #error "Please include Eigen/Geometry instead of including headers inside the src directory directly."

这个报错是因为代码中检查了是否直接包含AlignedBox.h，即在range.h中直接使用了

#include 

然后在AlignedBox.h中，有一个#include "./InternalHeaderCheck.h"直接检查了出来。
因此报错了，需要将range.h中的

#include 
修改为
#include
