how to solve error of Libara Library in Omnet?

Question

I am using

1. OMNET++ 5.4.1

2. Libara Library Version 1.2

3. clang version 5.0.1 (tags/RELEASE_501/final)

4. Target: x86_64-w64-windows-gnu

I am interested in the implementation of AntColony Optimization routing for VANET. After importing Libara Library : https://github.com/des-testbed/libara

Error : 0:58:48 **** Build of configuration clang-debug for project ARA-Simulation ****

make MODE=debug all

Compiling src/core/AbstractARAClient.cpp

clang++.exe: error: unsupported option '-fPIC' for target 'x86_64-w64-windows-gnu'

make: *** [Makefile:309: out/clang++-debug/src/core/AbstractARAClient.o] Error 1

I think there is a flag -fpic in makefile of Libara making the issue.

Compiler options

CFLAGS += -std=c++11 -fPIC

Help me to solve this issue. Thanks in advance.
