在Mac OS X上使用Cmake，链接库时需使用完整路径

我正在尝试使用cmake构建python扩展。以下是cmake列表：

cmake_minimum_required(VERSION 2.8)
PROJECT(drtile)
set(CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR})
find_package(Vigra REQUIRED)
find_package(Boost COMPONENTS python REQUIRED)
find_package(PythonLibs REQUIRED)
find_package(Numpy REQUIRED)

include_directories(
    ${VIGRA_INCLUDE_DIR}
    ${PYTHON_NUMPY_INCLUDE_DIR}
    ${Boost_INCLUDE_DIR}
    ${PYTHON_INCLUDE_DIRS}
    ${PYTHON_INCLUDE_PATH}
)
add_library(drtile SHARED drtile.cpp)
message("xxx ${Boost_PYTHON_LIBRARY} ${VIGRA_NUMPY_CORE_LIBRARY}${VIGRA_NUMPY_IMPEX_LIBRARY}")
target_link_libraries(drtile ${Boost_PYTHON_LIBRARY} ${VIGRA_NUMPY_CORE_LIBRARY}  ${PYTHON_LIBRARY})
IF(WIN32)
   SET_TARGET_PROPERTIES(drtile PROPERTIES OUTPUT_NAME "drtile" PREFIX "" SUFFIX  ".pyd")

ELSE()
    SET_TARGET_PROPERTIES(drtile PROPERTIES OUTPUT_NAME "drtile" PREFIX "" SUFFIX ".so")
ENDIF()

图书馆已经被正确编译和链接，但当我用otool查看链接库时，我得到了以下信息：

otool -L drtile.so

drtile.so:
/Users/lfiaschi/phd/workspace/lazyflow/lazyflow/drtile/drtile.so (compatibility version 0.0.0, current version 0.0.0)
libboost_python.dylib (compatibility version 0.0.0, current version 0.0.0)
vigranumpycore.so (compatibility version 0.0.0, current version 0.0.0)
/Users/lfiaschi/Library/Frameworks/Python.framework/Versions/2.7/Python (compatibility version 2.7.0, current version 2.7.0)
/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.11)

我该如何让CMake使用vigranumpycore.so和libboost_python.dylib的完整路径链接drtile.so呢？谢谢！

您遇到了rpath规则的问题。我认为您可以通过添加以下行来解决它

set(CMAKE_INSTALL_RPATH_USE_LINK_PATH TRUE)

在 PROJECT 命令之前。
