Improve CMake exported targets.

Browse Source 
I _think_ this represents some of the "best practices" for exporting
targets. They'll be available in a `googletest::` namespace (e.g.
`googletest::gmock`) with non-namespaced `ALIAS` targets.

- Added GOOGLETEST_VERSION variable
- Use `CMakePackageConfigHelpers`, bump minimum CMake version to 2.8.8
