c++ - 如何解决：没有规则来制作目标`/home/xxxxx/opencv-3.4.5/build/lib/libopencv_stitching.so.3.4.5'，需要`xxxxx'。停止

问题描述

我认为这里发生的问题几乎相同。

我做了这个问题的评论和回答，在CMakeLists.txt中添加了set(OpenCV_DIR xxxxx/opencv-3.4.5/build)……但是还是和下面一样的错误。

有人可以帮助我吗？先谢谢了！

这是我的 CMakeLists.txt：

cmake_minimum_required(VERSION 3.1)

# Enable C++11
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED TRUE)

# Define project name
project(xxxx)

set(OpenCV_DIR xxxxx/opencv-3.4.5/build)
find_package(OpenCV REQUIRED)

message(STATUS "OpenCV library status:")
message(STATUS "    config: ${OpenCV_DIR}")
message(STATUS "    version: ${OpenCV_VERSION}")
message(STATUS "    libraries: ${OpenCV_LIBS}")
message(STATUS "    include path: ${OpenCV_INCLUDE_DIRS}")

add_executable(xxxx xxxx.cpp)

target_link_libraries(xxxx ${OpenCV_LIBS})

这是 CMake 的日志。好像成功了

解决方案

不太确定，但您是否尝试过更改

set(OpenCV_DIR xxxxx/opencv-3.4.5/build)

不应该

set(OpenCV_DIR xxxxx/opencv-3.4.5/)

或者只是尝试预构建opencv，然后将它与您的可执行文件链接起来。

编辑1：

从 opencv_root_dir/build

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..
# use 3 cores to compile
make -j3

然后

# will install it to /usr/local )
sudo make install

添加到您的 cmake 文件中：

# adds the lib folder to not specify prefix everytime
link_directories( /usr/local/lib/ ) 
target_link_libraries( "<all opencv libs from /usr/local/lib>" )

# adds the includes (dunno if this needed but had to do it in my project)
# but I think only if opencv includes are not located in your project
# root dir
target_include_directories( "/usr/local/include/opencv" or "/usr/local/include/opencv2"  ) # depends what you use

尚未对其进行测试，但它对我的项目有所帮助。好消息是您不必每次都重新构建所有 opencv 文件。我还使用 *.so 文件链接。*.a 对我不起作用，但请自己尝试。
