# Finds a file in a package and assigns it to the given variable.

# Example:
#
# $(eval $(call onlpm_find_file,KERNEL_4_14,onl-kernel-4.14-lts-x86-64-all:amd64,kernel-4.14-lts-x86_64-all))

# The --find-dir equivalent.

# Just like onlpm_find_{file,dir} but also add the result to another variable for easier aggregation.
