Some libraries are not found without LD_LIBRARY_PATH mangling

No.

CMake generates -Wl,-rpath, which sets RPATH but not RUNPATH.

If we add -Wl,--enable-new-dtags, then the very same -Wl,--rpath flag will set 
both RPATH and RUNPATH to the same value.

Locally, I modified my gcc specs file to add the --enable-new-dtags flag 
always to the linker, so I don't have to worry about CMake or qmake support. 
(I routinely change my LD_LIBRARY_PATH to load different libraries in order 
to test regressions)
