Pytest-cmake

What's Changed

* Updated CMake script to ensure that environment variables preserve the Windows-style path syntax when running the tests (https://github.com/buddly27/pytest-cmake/issues/22)
* Improve tests.

**Full Changelog**: https://github.com/buddly27/pytest-cmake/compare/0.5.2...0.6.0

Updated test collection logic to ensure that the 'rootdir' is a real path. Previously, running the tests from a symlinked directory could result in errors when discovering 'conftests' configurations.
