CMAKE_AUTOGEN_VERBOSEΒΆ
New in version 3.13.
Sets the verbosity of AUTOMOC, AUTOUIC and
AUTORCC. A positive integer value or a true boolean value
lets the AUTO* generators output additional processing information.
Setting CMAKE_AUTOGEN_VERBOSE has the same effect
as setting the VERBOSE environment variable during
generation (e.g. by calling make VERBOSE=1).
The extra verbosity is limited to the AUTO* generators though.
By default CMAKE_AUTOGEN_VERBOSE is unset.
