Question

因此，我正在使用CMake（在Mac OS上）构建C ++项目，而我的项目依赖于dylib（我正在使用TBB https://www.threadingbuildingblocks.org/，但是特定的库本身并不重要）

如果我执行标准的“ cmake”和“ make”操作，则会在需要的位置生成可执行文件，并且在运行我的应用程序时，dylib可以正确链接，并且一切运行正常。

当我尝试执行“进行安装”并尝试从安装目录运行生成的可执行文件时，就会出现问题。我收到“找不到图像”错误：

dyld: Library not loaded: @rpath/libtbb.dylib
Referenced from: 
/Users/MyName/Desktop/ProjectRoot/install/./MyApp
Reason: image not found

有趣的是，如果我执行常规的“ make”而不进行安装，然后将可执行文件手动复制到安装目录，则该将正确链接到我的dylib。我不知道为什么会这样。

我的目录结构如下：

Root 
    CMakeLists.txt 
    Source/ 
    Libraries/ 
        tbb/ 
            include/ 
            lib/ 
                libtbb.dylib
    install/

...并且我的CMakeLists.txt文件如下：

# Start of CMakeLists.txt
cmake_minimum_required(VERSION 3.3)
project (MyApp)

# Set C++ version and output paths
set (CMAKE_CXX_STANDARD 14)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_SOURCE_DIR})
set(CMAKE_MACOSX_RPATH 1)
set(CMAKE_INSTALL_PREFIX "${CMAKE_SOURCE_DIR}/install")
set(CMAKE_INSTALL_RPATH "${CMAKE_INSTALL_PREFIX}/lib")

# Find TBB
find_library (
    TBB_LIBRARIES
    NAMES tbb libtbb # what to look for
    HINTS "${CMAKE_SOURCE_DIR}/Libraries/tbb/lib" # where to look
    NO_DEFAULT_PATH # do not search system default paths
)

# Set Custom Include Files + TBB header files 
include_directories(Source/Headers Libraries/tbb/include)


# Set Source Files
file(GLOB_RECURSE SRC_FILES "Source/*.cpp")
add_executable(MyApp ${SRC_FILES})

# Link Libraries 
target_link_libraries(MyApp ${TBB_LIBRARIES})

# Set compile flags
set_target_properties(MyApp PROPERTIES CXX_STANDARD 14) #LINK_FLAGS "-Wl")
target_compile_features(MyApp PUBLIC cxx_std_14)

# Install executable
install(TARGETS MyApp DESTINATION .)

如果我还尝试添加以下行，并同时安装dylib：

install(TARGETS ${TBB_LIBRARIES} DESTINATION lib)

然后，当我执行“ make install”时，出现以下错误：

install TARGETS given target 
"/Users/MyName/Desktop/ProjectRoot/Libraries/tbb/lib/libtbb.dylib"
which does not exist in this directory.

所以我似乎无法使该安装正常工作。我该如何修复它，以使我的可执行文件和库都安装在正确的位置，并且我的可执行文件在运行时能够链接到我的库？
