Do you mean "generator expressions" > on "configure+generate stage" vs "build stage"? > Generator expression came up because one needs to evaluate some variable value [apparently]at "build time" like knowing the exact name (with path) of a target (using TARGET_FILE generator expression in custom command). Knowing that "generator expression" are in fact evaluated during "generation step" and not really at build time is an implementation detail. (Which is a big one for implementors) but not really important to user. -- Craig Scott Melbourne, Australia http://crascit.com -- Eric
