cmake报错如下:
-- Configuring done
CMake Error: Cannot determine link language for target "math".
CMake Error: CMake can not determine linker language for target: math
-- Generating done
make报错如下:
make[2]: *** No rule to make target 'CMakeFiles/math.dir/build'。 停止。
CMakeFiles/Makefile2:67: recipe for target 'CMakeFiles/math.dir/all' failed
make[1]: *** [CMakeFiles/math.dir/all] Error 2
Makefile:83: recipe for target 'all' failed
make: *** [all] Error 2

这是添加了#include<assert.h>并且注释了代码中含有isnan的语句,然后编译的时候报错如下:

尊敬的老师您好：
我最近遇到了一个问题，问题是：我在做一个模型的评估的时候，通过评估方提供的数据集我重建后与评估方提供的标准模型对比时，发现两个模型的尺度不同，（相机姿态也不同，这个倒是可以align解决，但是两个模型的尺度不同，我一直没有搞清楚这个什么原因所引起的，是内外参吗？评估时 需要将两个模型放在同一个坐标系下，那么这个尺度问题，我如何将我自己生成的模型的尺度和评估方所提供的模型尺度一致呢）
非常感谢您在百忙中能够回复一下我的疑惑，感谢感谢！！

task7文件夹内的原有cmakelists中target_link_libraries(task7_texturing mvs util core texturing coldet mrf gco)改为target_link_libraries(task7_texturing mvs util texturing core coldet mrf gco)可编译通过，即替换了core texturing的顺序，原理未知。

task2，3，4相关主函数均存在此问题，手动添加后即可编译

贴图内存消耗很大，这样会极大地限制Mesh大小，关于减少内存消耗，有没有什么思路呢？

task5/class5_scene2pset_multi_views.cc:172:32: error: ‘arg’ was not declared in this scope
assert(util::string::right(arg.outmesh, 4) == ".ply");

这个怎么解决呀?我看到arg好像没有定义,不知道怎么修改,请求帮助,谢谢大家.
