Find_Package

find_package(COLMAP REQUIRED base exe controllers estimators feature optim sfm tools mvs util )

find_package里面的参数是就是这样，第一是在local 计算机上找package然后编辑。

第二个是我们可以不用使用全部package里面的so,o file。所以定一个条Require然后后面是只我们需要的source code或者我们可以特定的Version使用

经路：build/src/CMakeFiles/colmap.dir/controllers

在build里面的object file使用的

Manually add package condition

set( YOLO_INCLUDE_DIRS “${PROJECT_SOURCE_DIR}/third_party/darknet/include/”)

set( YOLO_LIBS “${PROJECT_SOURCE_DIR}/third_party/darknet/libdarknet.so”)

include_directories( ${PROJECT_HEADER_DIR} ${COLMAP_INCLUDE_DIRS} ${EZSIFT_INCLUDE_DIRS} ${DBoW2_INCLUDE_DIRS} ${EIGEN_INCLUDE_DIR} ${OpenCV_INCLUDE_DIRS} ${YOLO_INCLUDE_DIRS} )

Useful CMAKE

set(LIB_NAME “image_database_selector”)

target_link_libraries(${LIB_NAME}_lib ${OpenCV_LIBS} ${DBoW2_LIBS} ${EZSIFT_LIBS})

cmake编译错误”relocation R_X86_64_32 against .rodata can not be used when making a shared object“解决办法

在CMakeLists.txt中添加如下一行: add_definitions(-fPIC)

static library를 쓰려면 이를 추가해야 된다.
