Description
I have a tags target:
run_target('tags', command : ['etags', '-o', '@0@/@1@'.format(meson.source_root(), 'TAGS')] + all_files)
(The presence of etags is not checked first with find_program on purpose: I want the target to be always there, and just fail with an error message is the program is not found. And I don't want to spam normal builds with a message about a missing etags program, because most users won't need it.)
When this target is executed and ctags is not installed, the message is useless:
$ ninja -C build ctags
[0/1] Running external command ctags.
Could not execute command "ctags".
FAILED: ctags
'/usr/bin/python3' '/home/zbyszek/src/meson/meson.py' '--internal' 'commandrunner' '/home/zbyszek/src/casync' '/home/zbyszek/src/casync/build' '' '/home/zbyszek/src/meson/mesonintrospect.py' 'ctags' '-o' '/home/zbyszek/src/casync/tags' ...
ninja: build stopped: subcommand failed.
I'd expect the usual:
meson: ‘ctags’: No such file or directory
