@JonB Thank you sir, you right.

I did mistake in .pro file. I mention DEFINE like below.
DEFINES += WIN64 SQUIDSTATELIBRARY_LIB. To solve this error replace I replace to DEFINES += SQUIDSTATELIBRARY_LIB and it is work.

I don't know some how it is work on mac, but on Linux it was giving me error.

Thank you.
