file(WRITE "stuff containing above string")

the file is written with   "$<TARGET_FILE:hg_test_server<FILE:///\\hg_test_server>>" inside it, and not the full path/name of the target as I'd hoped.

Is there a way to force the evaluation of the generator expression so it is correctly written out into the launch script?


file(WRITE) is run at configuration time. Generator expressions are evaluated after configuration has finished (at generation time).
You can use file(GENERATE) to create files with generator expressions expanded at generation time.
