Hi there,
Our project installs an empty directory for other programs to drop files
in, the location of which is overrideable with a cache variable. Some
environments set the location of this directory outside the writeable
area and create it themselves, so I'd like to set up CMake so that it
tries to create the directory but skips over it if there is a failure.
At the moment we use:
SET(extra_completionsdir
${rel_datadir}/fish/vendor_completions.d
CACHE STRING "Path for extra completions")
INSTALL(DIRECTORY DESTINATION ${extra_completionsdir})
but that fails if the destination is not writeable.
Is there an idiomatic way of ignoring a failed installation step? At the
moment, I'm trying various install(script code execute_process(...
incantations, but I'm aware there's lots of corner cases with DESTDIR and
so on.
Thanks
David Adam
