Expected behavior

It works just like in linux.

Actual behavior

Error: Could not find include file ../../../libs.tech/ngspice/parasitics/sky130_fd_pr__model__parasitic__diode_pw2dn__extended_drain.model.spice
Error: Could not find include file ../../../libs.tech/ngspice/parasitics/sky130_fd_pr__model__parasitic__diode_ps2dn__extended_drain.model.spice
