Windows wireshark custom plugin loading error
I developed a custom wireshark dissector plugin on linux debian on wireshark 4.2.5 (also working on 4.2.6) which is working completely fine. However, when I try to use the source code from this plugin and do a custom build on Windows 11 wireshark 4.3.0 (following the documentation instructions to build from VS Code), I get the following error:
Couldn't load plugin 'wibotic.dll': 'C: \Development\wsbuild64\run\RelWithDebInfo\plugins\4.3\epan\wibotic.dll': The specified module could not be found.
The file exists at the above file path, so I'm not sure why it can't load it. For reference, I changed the top-level CMakeLists.txt and custom_plugins.txt files in accordance with the README.plugins. I also changed plugins.wxi, adding my custom plugin after the comments. Any help would be greatly appreciated!
Info about the build and runtime environment:

This used to occur if folks mixed up x64 and x86 builds in the same build directory. As we don't build x86 now this should be less likely.
I would delete the
\Development\wsbuild64directory and create a new one and run the cmake .. msbuild steps again.You also mention VS Code build docs, what are they? The Wireshark Developers Guide uses command line builds and note the warning in that doc about deviating from that process.

Are you doing a full build of Wireshark or just building the plugin?

From README.plugins:
Was the source updated when moving from the 4.2.x systems to 4.3.0 system?
@grahamb I am building using the command line following the instructions found here: https://www.wireshark.org/docs/wsdg_h... I believe this means that I'm using the correct compiler (MSVC 19.40.33811.0). I am also building for x64
@Chuckc I am doing a full build of wireshark with the hope of being able to create a Wireshark Installer. Rebuilding gives the same error.
The source was not updated when moving from systems. I tried to update it according to plugins.example, but that just gave me errors saying that plugin_version, plugin_want_major, etc were already defined. Also, there is something in the CMakeLists.txt in my plugin folder that says:
This is the same as the gryphon plugin, which does not have any errors. Is there anywhere else I need to ...(more)
set module info()sets the plugin version.plugin_want_majorandplugin_want_minorare the Wireshark version required to run and should be set by the build process.Can you update the question with output of
