# TO MATCH FILES RECURSIVELY
## recursive wildcard
## use it like `SRC := ${call rwildcard, ., *.c *.o *.s}`
rwildcard := ${foreach d,${wildcard ${1:=/*}},${call rwildcard,$d,$2} ${filter ${subst *,%,$2},$d}}

## use find cmd
## NOTE: I prefer this one
SRC := ${shell find . -type f -name *.c -or -name *.o}
