Question

我在一个文件夹中写了一系列包，我想编写一个使用它们的程序。最重要的是，我希望将文件夹保持在同一级别，以便拥有更独立的管理。例如，我有一个名为brisk的包，必须由另一个名为place_recognition

的包使用

cpp
 |
 -- brisk
 |  |
 |  --CMakeLists.txt
 |  |
 |  --release
 |  |  |
 |  |  --lib
  --etc...
 -- place_recognition
 |  |
 |  --cmake
 |  |
 |  -- CMakeLists.txt
 |  |
 |  -- src
 |  | 
 |  -- include

我写了一个FindBrisk.cmake文件，并将其添加到我的“place_recognition”项目中。

get_filename_component（BRISK_CURRENT_CONFIG_DIR “$ {CMAKE_CURRENT_LIST_FILE}”路径“

set(BRISK_EXPORTED_BUILD_DIR ${BRISK_CURRENT_CONFIG_DIR})
get_filename_component(BRISK_EXPORTED_SOURCE_DIR
  ${BRISK_EXPORTED_BUILD_DIR}/../../brisk/ ABSOLUTE)


set(BRISK_INCLUDE_DIR "${BRISK_EXPORTED_SOURCE_DIR}/include")
set(BRISK_LIBRARY_DIR "${BRISK_EXPORTED_SOURCE_DIR}/release/lib")
set(BRISK_FOUND True)
set(BRISK_LIBRARIES "${BRISK_EXPORTED_SOURCE_DIR}/release/lib/libbrisk.a")
set(AGAST_INCLUDE_DIR "${BRISK_EXPORTED_SOURCE_DIR}/agast/include")
set(AGAST_LIBRARIES "${BRISK_EXPORTED_SOURCE_DIR}/release/lib/libagast.a")
set(AGAST_FOUND True)

mark_as_advanced(BRISK_INCLUDE_DIR BRISK_LIBRARY_DIR BRISK_LIBRARIES AGAST_INCLUDE_DIR AGAST_LIBRARIES)

我将它包含在我在此处报告的CMakeLists.txt中

cmake_minimum_required(VERSION 2.8.11)

project(place_recognition)

#set up the output tree
set(CMAKE_BINARY_DIR ${PROJECT_SOURCE_DIR})
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib)
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)

set(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake)

find_package(Brisk REQUIRED)
find_package( OpenCV REQUIRED )
include_directories(BEFORE ${OpenCV_INCLUDE_DIRS}) 

if(BRISK_FOUND)
  message(STATUS "Found BRISK in " ${BRISK_INCLUDE_DIR})
else(BRISK_FOUND)
  message(STATUS "BRISK NOT FOUND")
endif(BRISK_FOUND)




# copy all needed files to binary dir (when cmake)
file(GLOB files_needed
    dataset/*
)
file(COPY ${files_needed} DESTINATION ${CMAKE_RUNTIME_OUTPUT_DIRECTORY})

include_directories(
  include
  ${BRISK_INCLUDE_DIR}
  ${AGAST_INCLUDE_DIR}
)



add_definitions(-mssse3 -DAGAST_GLOG -Werror -Wextra -Wall -pedantic -std=c++0x)

add_executable(
  ${PROJECT_NAME}
  src/main.cpp
)

link_directories(
    ${BRISK_LIBRARY_DIR}
)


target_link_libraries(
  ${PROJECT_NAME}
  ${OpenCV_LIBS}
  ${AGAST_LIBRARIES}
  ${BRISK_LIBRARIES}
)

然而，我得到了一个奇怪的行为。当我尝试编译代码时，编译器无法找到brisk包的依赖项，我被要求将它们显式包含在我的cmake文件中，在我的示例中，我必须使用OpenCV。因为，轻快使用GLOG现在我在尝试编译时遇到以下错误

我做错了什么？谢谢安德烈
