Added redhat/centos spec file

[kayrus]

Please have a look and let me know if you have any questions.

Your spec file uses cmake to build. The cmake files were provided from a third party for Windows, on Linux we have been using the normal make files. I am not sure the cmake stuff has all the right options etc. Maybe you want to use the make version and/or check whether they are in sync.

Cmake works well under Linux. As for normal make, I'll implement it in next versions. Thanks!

What's the reason for the extra libdir? Maybe we can roll the patch into the source?

[kayrus]

64bit and 32bit architectures have different libdir:
/usr/lib64
and
/usr/lib

[joto]

Let's pull that patch into the Makefile then. It doesn't hurt anybody else and everything becomes simpler.

Why are there the extra "mkdir ..." and "install..." lines in the %install section? Shouldn't the "make install" take care of that?

Build requirement for cmake is now not needed make, I guess.

Fixed.
