Fir them out and don't attach directly to the concrete block. Hang 2x2 from the floor joists above or go all the way from floor joist to basement floor. Put your french cleats on the firring and hang your cabinets. After many years in construction I can tell you that if you attach wood cabinets directly to a masonry basement wall, you are almost CERTAIN to have issues.
#1 I am very much against making holes in block that's below grade.
#2 Warm wood cabinets + concrete below grade = condensation
I'd keep an air space between the back of the cabinets and the block and I'd hang them either on a curtain wall or on runners suspended from the joists above.
Above grade you might be able to talk me into it.... maybe..... but I doubt it....
Below grade, not a chance
