About build osgearth, throw lnk2001 with gdal

[YHLpuyu]

The source code:

• osgearth (master)
• osg (master)
• gdal(3.7.1/3.9.1)
  I can build gdal, osg(with gdal) susccessfuly. when build osgearth, there are always 12 error LNK2001, some functions from gdal can't be link.

I confired the lib of gdal is set correctly, and all librarys is build with x64, c++14.
I also run some example of gdal, it works well
Is there some special things I missed? I also try download gdal from gisinternal, and configurate it into osgearth, always those 12 lnk errors.
I also use dumpbin export all funcitons from gdal.lib, I can see those functions in lib.
I'm confused! Thanks so much for anyone who can help!

Are you building GDAL yourself? Or getting it from vcpkg?

[YHLpuyu]

I builded gdal from source code, and download gdal from website gis internal. both lib can throw lnk2001 error

[YHLpuyu]

I try use gdal(3.8.3) from vcpkg, same errors, and new two error about ogr.
Maybe I change some config of osgerath, that effected.

[gwaldron]

Sorry I do not know the problem; cannot reproduce it locally. I am using GDAL 3.9.1 from vcpkg as of this writing.

thanks, I will try again if I'm free
