Comment (by kencu):

 Just so you know, and to make things terribly unclear,
 {{{CMAKE_BUILD_WITH_INSTALL_RPATH}}} has nothing to do with {{{@rpath}}}
 at all.

 {{{CMAKE_BUILD_WITH_INSTALL_RPATH}}} tells cmake whether to use the final
 installed libnames during the build, or whether to use temporary names (to
 their locations during the build) and then rewrite these names when
 destrooting happens to their final installed names.
