[CMake] CMake Error: RPATH_CHANGE

[Marcel Loose]

Hi all,

I encountered the following problem when trying to 'make install' a
statically linked executable on a ppc64 platform. 

CMake Error at cmake_install.cmake:47 (FILE):
  file RPATH_CHANGE could not write new RPATH:

    /tmp/loose/cmake/cmake-rpath/install/lib

  to the file:

    /tmp/loose/cmake/cmake-rpath/install/bin/greetings

  No valid ELF RPATH or RUNPATH entry exists in the file;

I could not reproduce this on a x86_64 platform. It seems that the
generated file cmake_install.cmake is the culprit. Diff-ing the file
generated on the ppc64 system with that generated on the x86_64 system
yields:

Both cmake 2.6.4 and 2.8.0-rc5 show this behaviour, which looks like a
bug to me.

Best regards,
Marcel Loose.
