Fix cmake install path issue

[gzzi]

Hi,

I compile using cmake:

cmake -DHAVE_RULES=ON -DUSE_MATCHCOMPILER=On ..

I see on the log:

-- FILESDIR =              OFF
-- FILESDIR_DEF =          /usr/local/share/Cppcheck

and when it install I got:

-- Install configuration: "Debug"
-- Installing: /usr/local/bin/cppcheck
-- Installing: /usr/local/OFF/addons/__init__.py
-- Installing: /usr/local/OFF/addons/cppcheck.py
...
-- Installing: /usr/local/OFF/cfg/avr.cfg
-- Installing: /usr/local/OFF/cfg/bento4.cfg
...
-- Installing: /usr/local/OFF/platforms/aix_ppc64.xml
-- Installing: /usr/local/OFF/platforms/arm32-wchar_t2.xml
-- Installing: /usr/local/OFF/platforms/arm32-wchar_t4.xml

and of course when running cppcheck I got:

Your Cppcheck installation is broken, please re-install. The Cppcheck binary was compiled with FILESDIR set to "/usr/local/share/Cppcheck" and will therefore search for std.cfg in /usr/local/share/Cppcheck/cfg.

Thanks for your contribution.

This has already been submitted as #6764. I hope to get around to this over the weekend.
