Improve pip installation

- Add cmake dependency in pyproject.toml
- Fix attempting to configure cmake with different generators
	Ninja was set in the CmakeCache, affecting the second attempt.
- Additional error handling in setup.py

Exceptions are raised when installation fails,
prints contain additional info and are only shown
when pip is run with -v flag.
