Is it possible to invoke a script function as part of a target? I have a build step where I need to process a bunch of variable values before building a particular target. All of the custom targets require a COMMAND, not a function. I thought maybe I could push this off to a script invoked by cmake -P, but a quick test revealed that the script does not inherit the variable environment and the variables I'm working with cannot be easily passed using -D values on the command line.
Script mode (-P) is the only way to invoke a cmake script function as part of a custom target. If passing values via -D is problematic perhaps you could generate the scripts themselves (e.g. configure_file()) or generate an include file for the script with the required values (and pass its path with -D).
