Making: set-up without tests still requires tests

[aoeftiger]

The make fails when trying to compile the tools having set the unit tests and benchmarking tests OFF in the Settings.cmake. (Based on gcc 9.1.0 and cmake 3.11.1.)

Settings.cmake

PS: this happens when trying to circumvent #67 which fails 3x for tests/ or examples related files -- so I tried to switch off the examples and tests in Settings.cmake

Pull request #68 should take care of this problem, please re-open if the problem persists
