Building Cef clone 140.1.14, my build of libcef.dll is much smaller than the same version from NuGet package 140.1.14

[BillBogart]

I am building Chrome cef version 140.1.14.0 to add h.264 & 256 video codecs.
I started with this article on how to do it:
https://scalibq.wordpress.com/2024/08/16/how-to-build-your-own-cef-with-mp4-support/

The problem I am having is that my build of libcef.dll is much smaller than the version that comes in the NuGet package. I have verified that they are the same exact version:
140.1.14+geb1c06e+chromium-140.0.7339.185

I am new to building Chrome Cef but I suspect something is missing/not linking statically.

After replacing NuGet package’s libcef.dll and chrome_elf.dll, CefSettings constructor gets the following runtime error:
System.IO.FileNotFoundException: 'Could not load file or assembly 'CefSharp.Core.Runtime.dll' or one of its dependencies. The specified module could not be found.'

I know its my built libcef.dll and chrome_elf.dll because replacing them with the original Nuget binary versions everything loads fine and it runs without any issues.

Here are the parameters I use for update.bat:
set GN_DEFINES=is_component_build=true ffmpeg_branding=Chrome proprietary_codecs=true
set GYP_MSVS_VERSION=2022
set CEF_ARCHIVE_FORMAT=tar.bz2
python3 ..\automate\automate-git.py --download-dir=c:\code\chromium_git --branch=7339 --minimal-distrib --client-distrib --force-clean --no-chromium-history --with-pgo-profiles

Here are the parameters I use for create.bat:
set GN_DEFINES=is_component_build=true ffmpeg_branding=Chrome proprietary_codecs=true
set CEF_ARCHIVE_FORMAT=tar.bz2
set GN_ARGUMENTS=--ide=vs2022 --sln=cef --filters=//cef/*
call cef_create_projects.bat

The resulting local built 32 bit release libcef.dll is 134,784 Kb
The NuGet 32 bit version libcef.dll is 203,906 Kb

Any help with what I am doing wrong would be greatly appreciated.

Thanks,
