        __declspec(dllimport) is used when compiling under Windows, and for MSVC only I think. So somehow I think that is what your compilation has been configured for?

            @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.
