Vivado synthesis failed for source RTL

[beef9]

Hello, I am trying to compile the source RTL files in Vivado 2023.2, however, I have the following errors: [Synth 8-36] 'lwc_config' is not declared [/sources_1/new/NIST_LWAPI_pkg.vhd":60] [Synth 8-439] module 'LWC' not found [Common 17-69] Command failed: Vivado Synthesis failed

I have added all .vhd files in the ascon-hardware/hardware/src-rtl (FIFO.vhd, LWC.vhd, etc.) into my project, but when I click run synthesis, I get the above mentioned errors. Is there something that I am missing? This is the line that fails: constant W : natural := LWC_config.W;
