There was a problem hiding this comment.
So in summary set_property(TARGET ${ADD_UNIT_TEST_TARGET} PROPERTY POSITION_INDEPENDENT_CODE FALSE) does not work with mac and gcc v>=6, hence the workaround. Does the POSITION_INDEPENDENT_CODE give anything after this workaround, or we could just delete that line?

We could remove that line, it does not give anything to the tests.
However, the code below is just a workaround that we'll remove after a "few" years (:smiley:), so I would leave POSITION_INDEPENDENT_CODE here.
