Subject: [PATCH] cmake: Try and improve cleaning of builds when B==S
Precedence: list
Content-Type: text/plain; charset="UTF-8"
Content-Transfer-Encoding: 7bit

Currently if B==S for a cmake recipe, the build will not reconfigure. This patch adds 
code to remove the generated cmake files, meaning cmake will then be forced to regenerate
them. This forces cmake to see configuration changes it may not otherwise see.
