When I try to use pip to install something it says it cannot because it doesn't make cmake. When I try to install cmake:

C:\Python35>pip3 install cmake
Collecting cmake
  Downloading cmake-0.7.0.tar.gz (29.2MB)
    100% |################################| 29.2MB 14kB/s
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

You are using pip version 7.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' comm
and.

C:\Python35>pip3 install skbuild
Collecting skbuild
  Could not find a version that satisfies the requirement skbuild (from versions
: )
No matching distribution found for skbuild

I did:
python -m pip install --upgrade pip

and then
pip3 install cmake
went OK.

So I would suggest to change notices like "You are using pip version 7.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' comm
and." into errors or warning so they seem more like something user has to do rather than something he might consider doing.

The pip issue tracker is at https://github.com/pypa/pip/issues if you want to suggest this, but I doubt it will be accepted.  The action *is* something optional.
