That's already 2 different standards for essentially the same thing (a
boolean option), and most non-GNU projects (and even some GNU ones) use them
pretty arbitrarily and inconsistently. (There is supposed to be a semantic
difference, but it is often arguable, because often a dependency and a
feature go together. And several upstreams just use the 2 variants
interchangeably altogether.)
In CMake, there's just:
-DTHING:BOOL=ON
-DTHING:BOOL=OFF
(and it also happily accepts a bunch of other notations for ON/OFF, without
the CMakeLists.txt having to do anything).
