Does CPack have any ability to help with the install_name_tool on

used by the application. My understanding is that the
install_name_tool essentially modifies the RPATH of the distributed
application so that it looks for the shared libraries in the bundle
rather than some random location. I have a script that I run to
make this all work, but it has to be modified as libraries change.
Or, if I somehow forget to run this step the whole distribution is
bad. Does CPack help with this?
In CMake 2.4 there is an INSTALL_NAME_DIR property that you can use
to control the install_name of the installed library or executable.
So this is actually part of the make install process then, right?
Yes, but it can be made to happen at build time too if you do not care
about running from the build tree (the BUILD_WITH_INSTALL_RPATH property).

If you get it working a Wiki entry would be great. Here is an example
to get you started (from memory):
ADD_LIBRARY(mylib SHARED ...)
SET_TARGET_PROPERTIES(mylib PROPERTIES
INSTALL_NAME_DIR "@executable_path/../lib"
)
ADD_EXECUTABLE(myexe ...)
TARGET_LINK_LIBRARIES(myexe mylib)
INSTALL(TARGETS mylib DESTINATION lib)
INSTALL(TARGETS myexe DESTINATION bin)
You'll have to modify this example to be bundle-specific.
