[CMake] text file modifications while Install

[Ilja Golshtein]

Hello, list,

please, suggest proper way to do some text file modifications while Install.

Basically I need something similar with RPATH change Cmake does,
but against a configuration file.

Currently I create amended version of the config make-time and
use it install-time. It does not look like an elegant solution.

Ideas how to do it better?

Thanks and sorry if double posted.
