Download and compile KchmViewer

As most open-source projects, Unix version of KchmViewer is distributed in source code package. To use it, you need to:

1. Download the latest version from SourceForge;
2. check that you have installed qt4-devel and chmlib-devel (or libchm-devel) packages, and install them if missing;
3. if you want to build KDE version, check that you have installed the appropriate development package and cmake;
4. unpack the downloaded archive;
5. read the README file for installation instructions

The Windows version comes in compiled form with the installer, so no need to compile anything. It, however, could be compiled using open source MinGW compiler with provided build-win32-mingw.sh script.
