This release adds support for building with cmake!
So switch to that eagerly instead of fighting with bam.
(if nothing else cmake is the devil we know...)
Also:
* fixup 'DATA_DIR' so programs can find resources
(without need for wrappers)
* install readme+license as previously done ("docs")
* don't install tools since not built or installed by default
* esp since doesn't appear to have non-adhoc method for installation
* other distros don't seem to include
