how to use it in my project

When I link the libethash.a ，I get the following errors
/usr/bin/ld: //usr/local/lib/libethash.a(ethash.cpp.o): relocation R_X86_64_32 against `__gxx_personality_v0' can not be used when making a shared object; recompile with -fPIC
//usr/local/lib/libethash.a: error adding symbols: Bad value

Configure CMake with -DCMAKE_POSITION_INDEPENDENT_CODE=TRUE. The official binaries should be already built like so.
