Dear sir,
I tried to build go-face project on win10 laptop,and I failed

FYI, this is my computer environment:
compiler: mingw64 with gcc8.1
os: windows10
golang version: 1.19 with cgo enabled
openblas: installed by this link(pre-built binaries): https://github.com/xianyi/OpenBLAS/releases
In face.go, I use:
// #cgo CXXFLAGS: -std=c++1z -Wall -O3 -DNDEBUG -march=native -IC:/OpenBLAS-0.3.23-x64/include -IC:/dlib/install/include -IC:/libjpeg-turbo-2.1.5.1/libjpeg-turbo-2.1.5.1/install/include
// #cgo LDFLAGS: -L C:/OpenBLAS-0.3.23-x64/lib -lopenblas -ldlib -ljpeg
// #include <stdlib.h>
// #include <stdint.h>
// #include "facerec.h"
import "C"

and I get below error, could you help me? It seems that dlib cannot find openblas library correctly, but I do have openblas on my computer:
