CMAKE_NO_BUILTIN_CHRPATH
------------------------

Do not use the builtin ELF editor to fix RPATHs on installation.

When an ELF binary needs to have a different RPATH after installation
than it does in the build tree, CMake uses a builtin editor to change
the RPATH in the installed copy.  If this variable is set to true then
CMake will relink the binary before installation instead of using its
builtin editor.
