It seems programs compiled (cmake, make, gcc-6.3, debian-9) with newer ITK (e.g. 4.12.2) set the RUNPATH in an executable (with CMAKE\_INSTALL\_RPATH\_USE\_LINK\_PATH TRUE) whereas compiling the same code with older ITK (e.g. 4.9.1) sets the RPATH.
This subtle difference seems to lead to the problem, that I get “error while loading shared libraries” when executing the installed program, even though `readelf -d /opt/ITK-CLIs/bin/hist | egrep 'RUNPATH|RPATH'` lists the correct RUNPATH. Starting the executable with LD\_LIBRARY\_PATH set to this RUNPATH lets the linker find the itk-libs, which makes me wonder whether the linker on my current system ignores the RUNPATH.
What can I do about that despite setting LD\_LIBRARY\_PATH?
How can I make the linker use RUNPATH or how can I compile with itk-4.12.2 such that RPATH is used instead?

Configuring/compiling with `SET(CMAKE_EXE_LINKER_FLAGS "-Wl,--disable-new-dtags")` makes programs linking to itk-4.12.2 use RPATH instead of RUNPATH. Running the installed executables then does not need LD\_LIBRARY\_PATH.
What is the best practice to deal with this RUNPATH problem?
