[Bf-committers] CMake minimum version increased to 3.0

[Bastien Montagne]

This is not correct, actually, install_deps.sh script does install/build 
missing dependencies for you, even on pretty old distributions.

We could (as suggested by Campbell this afternoon) do that for CMake as 
well (build newer one in install_deps.sh if needed),
but this is a bit a different case, user would not be able to use 
`cmake` directly from commandline, they’d have to remember
the path to the built cmake, would likely lead to a bunch of complains...
