No "usage.h" in the compilation

Hi all,

I follow the Setup manual to compile the binary fpix and riscv. I.e., I execute ./setup in my Linux server. However, I encountered an error that said no usage.h is found in fpix/src/load_program_options.cc.

Enclosed, please find my screenshot. It seems that the file usage.h is missing in the project, which causes the error.

My Linux server is CentOS 7.9.2009 with g++ 9.2.0 and Python 3.8

Thank you in advance.

Best regards, Chen
