Commit 73cc5089 (Using target_compile_features to specify C++ 11
standard) bumped the required cmake version, from 3.0 to 3.8, so
as to get the definition of target_compile_features().

However, target_compile_features() was introduced in cmake-3.1:
    https://cmake.org/cmake/help/v3.1/command/target_compile_features.html

And using cmake-3.1 is indeed sufficient to properly build.

As such, relax the minimum required version down to cmake-3.1,
so we can build on oldish, entreprise-grade distributions that
only have cmake-3.1 (or at least, don't have up to cmake-3.8).
