Build: Fix RPATH handling CMAKE_INSTALL_RPATH has to be set before the targets are defined (oops.) This also explicitly turns on MACOSX_RPATH for the shared libraries (which is the default with newer versions of CMake but not with 2.8.x.) The old autotools/libtool build system hard-coded the install name directory of the OS X shared libraries to libdir, which meant that any executable that linked against those libraries would also be hard-coded to look for the libjpeg-turbo libraries in that directory. @rpath makes the OS X version of libjpeg-turbo behave like the Linux version, in the sense that the executables under /opt/libjpeg-turbo/bin will automatically pick up the libraries under /opt/libjpeg-turbo/lib* by default, but other executables won't unless they are linked with -rpath.
