If you mean adding @lazfpc.cfg to options -- I tried it,
it did not work.
If you mean editing global fpc.cfg, then building,
then editing it back -- this seems too cumbersome.
Is this really the only way? IIUC, some people always build Lazarus with -Cr
I wonder how do they achieve it without hampering other projects?
