Upgrade the autobuild script

This update the autobuild script generated by the CMakeAfbTemplates
module making clearer build dir variable and change the way to build
using the classic way with cmake .. ; make etc.
Remove also an intermediate target that wasn't needed.

Change the directory where the autobuild script is generated.

Added a README instruction about the autobuild script coming from the
SPEC-495 description
