Issues compiling LiME for embedded Linux buildroot 4.15.7 kernel (armV71)

[mariya13-kirmani]

I am trying to cross-compile the LiME for Linux 4.15.7 kernel, and I have cross-compiled LiME for the said kernel, but it won't recognize the kernel and the generated lime.ko.
I made some changes in the Makefile that is shown below, but the actual .ko file is not generated. Does the LiME support the 32-bit ARM architecture?

Here is the excerpt of the Makefile:
obj-m := lime.o

I added the following line to cross-compile it for the arm

export KERNEL_ROOT=$(BASE_INSTALL_DIR)/Step-3/linux-4.15.7

lime-objs := tcp.o disk.o main.o hash.o deflate.o

KVER ?= $(shell uname -r)

#KDIR ?= /lib/modules/$(KVER)/build

KDIR ?= $(KERNEL_ROOT)
PWD := $(shell pwd)
.PHONY: modules modules_install clean distclean debug

default:
$(MAKE) -C $(KDIR) M="$(PWD)" modules
strip --strip-unneeded lime.ko
mv lime.ko lime-$(KVER).ko

debug:
KCFLAGS="-DLIME_DEBUG" $(MAKE) CONFIG_DEBUG_SG=y -C $(KDIR) M="$(PWD)" modules
strip --strip-unneeded lime.ko
mv lime.ko lime-$(KVER).ko

symbols:
$(MAKE) -C $(KDIR) M="$(PWD)" modules
mv lime.ko lime-$(KVER).ko

modules: main.c disk.c tcp.c hash.c lime.h
$(MAKE) -C /lib/modules/$(KVER)/build M="$(PWD)" $@
strip --strip-unneeded lime.ko

modules_install: modules
$(MAKE) -C $(KDIR) M="$(PWD)" $@

clean:
rm -f .o .mod.c Module.symvers Module.markers modules.order ..o.cmd ..ko.cmd .*.o.d
rm -rf .tmp_versions

distclean: mrproper
mrproper: clean
rm -f *.ko

After I make the file, I get the following output:
machine2@machine2-VirtualBox:~/online/embedded-linux/Step-6/kernel_fun/LiME/src$ arm-make
make -C /home/machine2/online/embedded-linux/Step-3/linux-4.15.7 M="/home/machine2/online/embedded-linux/Step-6/kernel_fun/LiME/src" modules

strip --strip-unneeded lime.ko

The lime.ko file is created:
machine2@machine2-VirtualBox:~/online/embedded-linux/Step-6/kernel_fun/LiME/src$ ls
deflate.c disk.c hash.c lime.h lime.mod.c lime.o main.o Makefile.sample Module.symvers tcp.o

Kindly please help me, I am new to this cross-compiling the kernel modules.
