Compilation issues with CoAP client.

Hello,
I am compiling the calvin-constrained with CoAP client and it fails. I am facing below-mentioned issues.

1. In the Makefile (runtime/south/platform/x86/Makefile) CC_FLAGS, CC_LDFLAGS, and CC_LIBS entries are not retrieved as pkg-config command could not set the values for CC_FLAGS, CC_LDFLAGS, and CC_LIBS for libcoap package.
   .....
   ifeq ($(LIBCOAP),1)
   CC_SRC_C += runtime/south/platform/x86/calvinsys/cc_libcoap_client.c
   CC_CFLAGS += -DCC_USE_LIBCOAP_CLIENT=1
   CC_CFLAGS += $(shell pkg-config --cflags-only-I libcoap-1)
   CC_LDFLAGS += $(shell pkg-config --libs-only-L libcoap-1)
   CC_LIBS += $(shell pkg-config --libs-only-l libcoap-1)
   endif
   .......

As I could not locate the libcoap package by default, I installed it manually but I am not sure what to put into the .pc file for libcoap to make pkg-config command succeed.

libcoap Package installed : libcoap-1-0:amd64 4.1.2-1 amd64 C-Implementation of CoAP

Could you please correct me if I am not following the right procedure to compile with coap client as compilation does not work for me out of the box.
Looking for your support.

Thanks!!
