It is another good reason for giving user a choice.

That could help, but only for 'make clean' part. Myself I rarely do it, 
rather I create new branches or modify CMakeLists.txt that forces KiCad 
to rebuild boost.

I am not sure if it will that way, but you may try to trim the beginning 
and the end of the patch. If it does not work, the crucial part is:

The rest is merely cleaning stuff, it does not influence build time.
