Hi Robert,
Thanks for your reply. We do use install_name_tool and the like when
installing/packaging, and our packages continue to work fine on OS X 10.12. My
question is about what to do with executables before packaging, while they are
still just in the build tree. We need them to work for purposes of testing via
CTest.

My general approach for the second problem is to run a tool such as
install_name_tool to change the library names to have @rpath when
constructing the package.

previously the linker was able to locate the boost libs for our build tree

(My understanding is, the boost project does that deliberately because they
can’t know what users of their libraries will want.)

That doesn’t solve the second part of the problem, though. Without embedding
install names that look like @rpath/libboost_foo.dylib in the build tree
executables, I think the linker will still be unable to find them.
