Comment # 6 on bug 1191473 from Stefan Br���ns

For AppCSXCAD, the failure reason is quite obscure:

On Leap 15.{2,3}, neither x86_64 nor aarch64 have an RUNPATH or RPATH entry,
but CMAKE_SKIP_INSTALL_RPATH is set, so cmakes `file(CHANGE_RPATH ...)` is not
invoked. No possibility to fail ...


On TW, i586 and aarch64 have a RUNPATH entry,
0x0000001d (RUNPATH)                    Library runpath: [::::::::]

while x86_64 on TW has not.

The latter seems incorrect to me, as the final linker command contains
"-Wl,-rpath,::::::::::" for all architectures on TW. CMake adds this option to
have a sufficiently large RUNPATH string entry (containing only padding from a
semantic view point) which can be overwritten during install.
