However, when it came time to actually set this IS_INTERROGATE property, I could find no way to apply it to a custom command. I guess this makes sense - custom commands aren't targets, after all. But I couldn't convert my custom command to a custom target, because it produces a C++ source file and I need to use OUTPUT to let CMake know where that source file comes from, and you can't use OUTPUT and TARGET together in add_custom_command.
Hi Sam: It's quite common for each custom command to have a corresponding custom target that DEPENDS on the OUTPUT of the custom command. So building the target part of that pair means the custom command is executed *only if* the OUTPUT from it is out of date. If you used that paradigm for the custom commands you refer to above (where each such custom command is paired with a unique target via the DEPENDS of the latter) could you not set the IS_INTERROGATE property for the custom target part of of each pair whenever that property is relevant?
