rusticl: set `OCL_ICD_VENDORS` as directory, not file
What does this MR do and why?
Looks like OCL_ICD_VENDORS
is meant to be a directory containing
.icd
files, but we were giving it a path to a driver.
This meant that rusticl
wouldn't get picked up when using devenv
.
I might be doing this totally wrong though, please let me know!
