What was the problem?
https://cmake.org/cmake/help/v3.27/prop_cache/TYPE.html
By default ON/OFF is a boolean type. You will have in issues where you
have two variables with different types and you want to override one or
both of them. For example:
set(NAME "Marc Espie" CACHE STRING)
set(NAME "/home/espie" CACHE FILEPATH)
If you want to override it with ARGS (-D) you have to set the type
-DNAME:STRING="Rafael Sadowski".
Cheers,
