    build-essential \
    libboost-program-options-dev \
    libboost-filesystem-dev \
    libboost-graph-dev \
    libboost-system-dev \
    libboost-test-dev \
    libeigen3-dev \

2. 安装

git clone https://github.com/colmap/colmap.git
cd colmap
git checkout dev(这个我报错了，没管）
mkdir build
cd build
cmake .. 
make -j10
sudo make install

3.运行

colmap -h

遇到问题
1.CMake Error at cmake/FindDependencies.cmake:124 (message):
You must set CMAKE_CUDA_ARCHITECTURES to e.g. ‘native’, ‘all-major’, ‘70’,
etc. More information at
https://cmake.org/cmake/help/latest/prop_tgt/CUDA_ARCHITECTURES.html
Call Stack (most recent call first):
CMakeLists.txt:87 (include)
解决办法
进入cmake/FindDependencies.cmake
添加以下代码

set(CMAKE_CUDA_ARCHITECTURES "70")

解决办法：该问题是anaconda的libtiff的问题，网上解决办法是

conda uninstall libtiff

我没试过这个方法.
我的解决方法如下
直接卸载anaconda
或者
在bashrc里注释掉anaconda路径
然后添加

conda deactivate

给anaconda文件夹改个名字
删除colmap/build里的文件，重新编译即可解决。
等编译完成再把路径改回来应该就可以
