[CMake] Make errors when running ./bootstrap in Ubuntu 12.04

[Robert Maynard]

The precompiled binaries would be your best option as they are built
with older platforms in mind.

If you try to build from source you should set the  CC and CXX
environment flags, as your output is mismatched ( it is grabbing clang
for C++, and gcc for C ).
