crypto++ library integration with omnet++

Question

I was trying to build cryptopp library with clang (as some one told me in a previous question)
I did as mentioned here: https://www.cryptopp.com/wiki/GNUmakefile
I used CXX=clang++ make in the library folder, But:

• In linux (ubunto), I was able to build the library successfully with clang and could include it in an omnet++ project, used it, and the project was built successfully. It worked fine.
• In Windows 10, I could build the library also with clang. But when I include it to a project in omnet++ and build, I get this error:
  The build log is here:

• In both cases (Linux and Windows), I added two link options in makemake for the library:
  -lcryptopp
  -lpthread

I want it to work fine in windows because all my work is on windows, and I only have linux on a virtual machine...
