我正在尝试创建然后将dylib添加到项目中.我使用"Cocoa-Library"模板创建它,并将类型设置为"Dynamic"(不确定它应该是动态的还是静态的......).然后我创建了一个名为Test的简单obj-c类,并在其中编写了一个打印出控制台的方法.

我编译并使用生成的.dylib文件并将其放在另一个项目中.现在每当我尝试使用它时,我都会在运行时收到此消息"

dyld: Library not loaded: /usr/local/lib/TESTLib.dylib
  Referenced from: /Users/***/Library/Developer/Xcode/DerivedData/TestingDYLIB-axmoocnxbwznoyerfogosumqufxc/Build/Products/Debug/TestingDYLIB.app/Contents/MacOS/TestingDYLIB
  Reason: image not found

我还创建了一个Copy File阶段并将目标设置为"Frameworks".我仍然得到同样的错误.我究竟做错了什么？谢谢.

我有一个项目，在子目录中包含opencv的预构建版本。例如：

MyProject
* CMakeLists.txt
* src
* third_party
** CMakeLists.txt
** opencv
****包括
**** lib

我想链接到位于third_party目录中的opencv版本。我的问题是，如何通知CMake链接到lib中的预构建dylib文件，并将标头包含在相关的opencv目录中？

cmake_minimum_required(VERSION 2.8.9)
project (myproject)

include_directories(${CMAKE_SOURCE_DIR}/third_party/opencv/include)
link_directories(${CMAKE_SOURCE_DIR}/third_party/opencv/lib)

file(GLOB SOURCES "*.cpp")

add_executable(myproject ${SOURCES})
target_link_libraries(myproject opencv_calib3d opencv_contrib opencv_core opencv_highgui opencv_features2d opencv_highgui opencv_imgproc)

我编写了一个cmake文件，该文件构建了两个共享库vector3.c和matrix4.c。matrix4依赖于vector3，如果我运行cmake项目并仅构建vector3共享库，则当我添加matrix4库我收到一个cmake错误。没有规则可以成为目标。
