Hmmm - I never felt the need for this. I just copy a library to my
system and add the directory to the list of directories to be searched.
What could possible be easier than that.

Hmmm - Now I don't know what the proposal is. I thought it was to
replace bjam. I don't know what else it needs to do. I see CMake as an
alternative way of building and testing libraries. I don't see this
impacting users in any way. I thought I knew what is being proposed but
now I don't think I do. Perhaps this proposal should be something more
specific than "Moving Boost to CMake".
