Hi Kire,

I have a bit of heartburn over constantly adding new directories to
look for QWT libraries. It seems like we would just be introducing a
new directory for every platform we want to work on.

The alternative way is to handle it by passing the directories to
cmake via the command line:

cmake -DQWT_INCLUDE_DIRS=/usr/include/qwt5

Since the library is in /usr/lib64, you don't need to tell cmake this,
since it's a standard library path already.

I added these directions to the wiki build guide for Suse:
