To build ShowImage, just extract the sources into some directory,
and use cmake to create the Makefile, e.g.:

cd <directory of sources>
mkdir build
cd build
cmake ..
make
make install  (as root)

You can then run the "showimage" executable passing it an image
filename to show, e.g.

showimage picture.png

or pass a directory to show the first image in it and allow to browse
through the dir with page-up/down
