Unable to Include cppzmq Library in OMNeT++ Project Makefile Description

[isha3026]

I'm encountering an issue while trying to include the cppzmq library in my OMNeT++ project Makefile. My goal is to use cpppzmq as a messaging library for co-simulation between Carla and OMNET++ CARLANeT (https://github.com/carlanet). I followed the instructions in the project's README (https://github.com/zeromq/cppzmq) and installed cppzmq using vcpkg. However, when I add the necessary flags to the Makefile to link against cppzmq, I'm still unable to access the header files, and the compilation fails with the error message "zmq.hpp file not found" (project's workspace screenshot with error attached below)

Here's (the bold lines) the relevant portion of my Makefile where I added the flags to include cppzmq:

all: checkmakefiles
cd src && $(MAKE)

clean: checkmakefiles
cd src && $(MAKE) clean

cleanall: checkmakefiles
cd src && $(MAKE) MODE=release clean
cd src && $(MAKE) MODE=debug clean
rm -f src/Makefile

makefiles:
#cd src && opp_makemake -f --make-so --deep -o carlanet -O out -KINET4_4_PROJ=../../inet4.4 -DINET_IMPORT -I$$(INET4_4_PROJ)/src -L$$(INET4_4_PROJ)/src -lzmq -lINET$$(D)
cd src && opp_makemake -f --make-so --deep -o carlanet -O out -KINET4_4_PROJ=../../inet4.4 -DINET_IMPORT -I$(INET4_4_PROJ)/src -L$(INET4_4_PROJ)/src -lINET$(D) -LC:/Users/uqipali/Documents/omnet/omnetpp-6.0.2/vcpkg/packages/zeromq_x64-windows/lib -llibzmq-mt-4_3_5 -IC:/Users/uqipali/Documents/omnet/omnetpp-6.0.2/vcpkg/installed/x64-windows/include

checkmakefiles:
@if [ ! -f src/Makefile ]; then
echo;
echo '=======================================================================';
echo 'src/Makefile does not exist. Please use "make makefiles" to generate it!';
echo '=======================================================================';
echo;
exit 1;
fi

Could you please advise on what needs to be corrected in order to successfully use cppzmq in my OMNeT++ project? Any assistance would be greatly appreciated. Thank you in advance :)
