I am writing a genrule in Bazel. I have a file withing a folder that may or may not exist. I want to reference it if it does but ignore it if it does not. How do i do an conditional check in the cmd part of the genrule before doing $(location my_file_that_may_or_may_not_exist)?
When the file does not exist I get
$(location) expression expands to no files error. This is expected so I want to avoid it
