Summary0015658: Allow generator expressions in add_custom_command (and add_custom_target)
DescriptionNow that LOCATION is disallowed, using a target path as an argument to a custom command is not possible without warnings (or making CMP0026 OLD).

At least OUTPUT, COMMAND, MAIN_DEPENDENCY, DEPENDS, WORKING_DIRECTORY, and SOURCES (for a_c_t) should expand generator expressions. Some may already do so via properties being genex-expanded already (just WORKING_DIRECTORY IIRC).

The COMMAND and DEPENDS already support generator expressions and have since the 2.8 era. The TARGET_FILE genex and its variants are very useful with these and were created specifically for the purpose of avoiding use of the LOCATION property.

Hmm. I will have to investigate why naked genex strings get dumped out into Ninja then.
