Scikit-build 0.6.1

Bug fixes

• Ensure CMake arguments passed to scikit-build and starting with -DCMAKE_* are passed to the test project allowing to determine which generator to use. For example, this ensures that arguments like -DCMAKE_MAKE_PROGRAM:FILEPATH=/path/to/program are passed. See #256.

Documentation

• Update Making a release section including instructions to update README.rst with up-to-date pypi download statistics based on Google big table.
