I am not able to figure out what does a dot . in front of a variable in makefile does. For e.g.:
SOURCEDIRS = . $(PROJECTDIRS) $(TARGET_DIRS_CONCAT)
vpath %.c $(SOURCEDIRS)
It would be great if someone could tell me. Thanks!

Generally it just refers to your current directory.
I.e. If you were on a linux machine, and you
cd /home/user/Darthand runls ., you should see the contents of the the folder Darth. So in this case, it looks like it's just including the current directory that you're in into theSOURCEDIRS.
