一、安装colmap

参考安装：chttps://blog.csdn.net/weixin_46132232/article/details/124211233

官方：COLMAP 官方information

二、报错解决

2.1 在安装colmap的时候 cmake ..出现下面报错，通过升级cmake得到解决(将原先的cmake 3.16 升级到最新版本cmake-3.24.3)

报错细节：

CMake Error at /usr/share/cmake-3.16/Modules/FindCUDA.cmake:1825 (add_library):
  Target "colmap_cuda" links to target "CUDA::cublas" but the target was not
  found.  Perhaps a find_package() call is missing for an IMPORTED target, or
  an ALIAS target is missing?

    runtime library [libgmp.so.10] in /usr/lib/x86_64-linux-gnu may be hidden by files in:
      /home/w/anaconda3/lib

  Some of these libraries may not be found correctly.

2.2 编译colmap时会出现

Make Warning at cmake/CMakeHelper.cmake:160 (add_executable):
Cannot generate a safe runtime search path for target colmap_exe because
files in some directories may conflict with libraries in implicit directories:

runtime library [libmpfr.so.6] in /usr/lib/x86_64-linux-gnu may be hidden by files in:
/home/w/anaconda3/lib
runtime library [libgmp.so.10] in /usr/lib/x86_64-linux-gnu may be hidden by files in:
/home/w/anaconda3/lib

解决办法：

更改anaconda3名字，安装colmap后改回来

2.3 make 的时候出现下面警告，但是不影响colmap的编译
