--- Comment #6 from Dawid Gajownik gajownik@gmail.com --- I would suggest changing in %build section
%{cmake} -DCMAKE_BUILD_TYPE=Debug
to
%{cmake} -DCMAKE_BUILD_TYPE=RelWithDebInfo
or removing option CMAKE_BUILD_TYPE altogether because RelWithDebInfo is a default option.

Debug disables all the optimizations and spills lots of debugging output on the console while the program is running.
RelWithDebInfo allows to create dubug packages and is more performance wise for the user.
