[CMake] RPM package and relocation

[Craig Scott]

You probably need to show us the postinstall script for us to be able to
see the problem. Also, in case you haven't found it already, the MaximumRPM
manual may be helpful (although it seems you've already found the
essentials and that document could be getting a bit dated by now):

http://ftp.rpm.org/max-rpm/

specifically chapter 15: Making A Relocatable Package and chapter 13:
Scripts: RPM's Workhorse. You might also want to check you are not having
the problem described in this stackoverflow answer
<http://stackoverflow.com/a/18543423/1938798> regarding when variables get
substituted.
