can you make a new version so its works with new colmap and glomap and new blender version.please

I made a docker based solution for the pipeline mainly for my mac that builds GLOMAP and COLMAP from source. Repo here.

If your computer is not in English you might run into the trouble of the bat file not working like me (My PC is Japanese, cmd appears for a second and crashes). What worked for me is to open the bat file in windows own basic notepad (not notepad++) and save the file again in ANSI (the drop down menu is at the bottom right corner of the 'save as' window).

Here is the step by step:
The Fix: Save as ANSI/Plain UTF-8

1. Open the standard Windows Notepad app.
2. Copy the original batch script text from your very first message and paste it into the blank Notepad window.
3. Click File > Save As...
4. Set the "Save as type" dropdown to All Files (.).
5. The Most Important Step: Look at the Encoding dropdown at the very bottom of the Save window. Change it to ANSI (If ANSI isn't available, select plain UTF-8, but strictly avoid "UTF-8 with BOM" or "UTF-16 LE").
6. Click Save (overwrite your old file if necessary).
7. Run the bat file again.
