I am trying to do this:
I want to call a make (Makefile exists in some other directory, abc path can be used) from a shell script located in a different directory. How do I do this?
Since shell scripting does not allow me to cd into the Makefile directory and execute make, how can I write the shell command (by giving path to the Makefile to be executed) to execute make?

Use cd ./dir && make && pwd inside Makefile . The && was exactly what I needed to change a directory and execute a command there, then drop back to the main folder to finish the build.
# Register all subdirectories in the project's root directory. SUBDIRS := $(wildcard */.) # Recurse `make` into each subdirectory. $(SUBDIRS): FORCE $(MAKE) -C $@ # A target without prerequisites and a recipe, and there is no file named `FORCE`.
You can use the -C flag to specify the path to your makefile. This way you can execute it from a different directory. The -f flag has a different use. With that flag you can execute a makefile with a name other than makefile .
GNU make accepts many options, notably -C to change directory before running, and -f for giving the Makefile to follow.
Combine them appropriately.
Consider using remake to ease debugging (notably with -x) of Makefile related issues. With GNU make version 4 or better, also use make --trace...
You could have your own executable shell script (e.g. in your $HOME/bin/ which would be in your $PATH) which uses both cd and make).
You could consider other build automation tools (ninja perhaps)
