【三维重建】openMVG单文件拎出来构建

开源软件下载下来之后如何进行改动，方法一就是在原来的工程基础上直接进行修改，使用开源软件自己的cmake方法进行构建。方法二就是将开源软件作为第三方库，将单个文件从工程里面单拎出来进行构建修改。
openmvg单个文件构建的cmake如何编写可以参考如下这个博客：

三维重建相关的几个程序是

main_SfMInit_ImageListing.cpp
main_ComputeFeatures.cpp
main_ComputeMatches.cpp
main_IncrementalSfM.cpp
main_GlobalSfM.cpp

cmake构建如下（拿main_SfMInit_ImageListing.cpp 示例）：

cmake_minimum_required(VERSION 3.0.0)
project(mvgtest1)
set(CMAKE_CXX_STANDARD 17)

add_executable(main_SfMInit_ImageListing main_SfMInit_ImageListing.cpp)

#OpenMVG,OpenCV,Ceres

find_package(OpenCV REQUIRED)
find_package(OpenMVG REQUIRED)

find_package(Ceres REQUIRED PATHS "${CERES_PATH}/Thirdparty/ceres-solver")
include_directories(${CERES_INCLUDE_DIRS})
set(LIBS ${Ceres_LIBS_DIR}/libceres.a umfpack cxsparse glog gflags gomp
        ccolamd btf klu cholmod lapack blas camd amd pthread)
include_directories(${OPENMVG_INCLUDE_DIRS})
