Cmake is bloat and wmfs doesn't need a complex build system
So now wmfs compile with a Makefile using gmake and pkg-config
compilation options can be customised through confix.mk (dwm like)
Remove doxygen config files (wmfs code doesn't use it, and nobody use
doxygen with wmfs)
Replace wmfsrc.in by wmfsrc (change @WMFS_TERM@ and use shell choice
urxvt || xterm || ...)
Remove generation of Changelog file (we can git log > Changelog before
creating a dist package)
Remove README from install process (this file don't need to be included in dist
package)
What's next before merging into master ?
- provide a BSD Makefile
- discuss if we use or not pkg-config (we can document common places
to include directory and libs in config.mk)
- compile out of tree
