Issue using FreeImage.lib in building colmap in Windows VS2022

[kindaichinisan]

LNK2019 unresolved external symbol getopt referenced in function main colmap_sensor_bitmap_test C:\Users\hwenjun\Documents\GitHub\colmap_cmaked_VS2\src\colmap\sensor\FreeImage_d.lib(mkg3states.obj)

Analysing mkg3states.c shows that it uses #include "libport.h" which has int getopt(int argc, char * const argv[], const char *optstring); but the implementation is not found anywhere in the project.

How to resolve this?
