[CMake] Runpath issues on OSX 10.6

[Quanah Gibson-Mount]

I've managed to get cmake to correctly build mysql on Linux OSes, but I 
have a continued problem with mysql on OSX.  Specifically, cmake does not 
install the mysql libraries with the correct RUNPATH settings.

For example, prior to installing to the destination path:

sh-3.2# otool -L libmysqlclient.18.dylib
libmysqlclient.18.dylib:
 
/Users/build/p4/main/ThirdParty/mysql/mysql-5.5.13/libmysql/libmysqlclient.18.dylib 
(compatibility version 18.0.0, current version 18.0.0)

After installation:
sh-3.2# cd /opt/zimbra/mysql-standard-5.5.13-apple-darwin10-i386/lib/
sh-3.2# otool -L libmysqlclient.18.dylib
libmysqlclient.18.dylib:
        libmysqlclient.18.dylib (compatibility version 18.0.0, current 
version 18.0.0)

This causes problems when linking to the library later on with other 
software.

I've attempted to fix this by adding various options to the CMakeLists.txt 
file:

SET(CMAKE_SKIP_BUILD_RPATH  FALSE)
SET(CMAKE_BUILD_WITH_INSTALL_RPATH FALSE)
SET(CMAKE_INSTALL_RPATH "${CMAKE_INSTALL_PREFIX}/lib")
SET(CMAKE_INSTALL_RPATH_USE_LINK_PATH TRUE)
LIST(FIND CMAKE_PLATFORM_IMPLICIT_LINK_DIRECTORIES 
"${CMAKE_INSTALL_PREFIX}/lib" isSystemDir)
IF("${isSystemDir}" STREQUAL "-1")
   SET(CMAKE_INSTALL_RPATH "${CMAKE_INSTALL_PREFIX}/lib")
ENDIF("${isSystemDir}" STREQUAL "-1")


However, no luck in resolving this problem.

Any help much appreciated!
