Sample project with RTL module library not working

Hello Intel Support, I am attempting to compile a library of RTL components to use in my HLS project. The HLS project compiles when testing for x86-64 simulation, but the compiler complains about...

    The issue is in my expHBU.h file. I put

    uint8_t expHBU(uint8_t input);

    extern "C" {
    uint8_t expHBU(uint8_t input);
}

    This extern is extremely esoteric and should be included in the reference manual.

Additional information: If I compile the library with just the fpga_crossgen command (exclude the expHBU.a step)

fpga_crossgen exp_wrapper.xml --target hls --emulation_model expHBU.cpp -o expHBU.o

And then attempt a -march=Cyclone10GX compile

i++ component_testbench.cpp expHBU.o  -v --dont-error-if-large-area-est -march=Cyclone10GX -o test-fpga

I get the following error

Compiler Error: Cannot find Library file ./test-fpga.prj/spec.xml
