I cloned Cheat Engine github repo and found that there are example for plugins. I opened `example-c` solution in Visual Studio 2019 on Windows 10.
Solution originally targets toolset v140 for Windows XP and Windows 8.1 SDK. I changed it to the ones installed on my machine: Windows 10 SDK 10.0.18362.0 and Platform toolset Visual Studio 2019 (v142).

With these settings it built the solution for Win32 platform and produced the example-c.dll, which I opened in Win32 Cheat Engine and it showed all the checkboxes as expected.

I then changed platform to x64 and tried to build, I get these errors:

Visual Studio does find the lua53-64.lib and use the x64 one and not Win32 one, when I rename the lua53-64.lib to lua53-642.lib, I get a different error about the fact that it can't fine the lua53-64.lib:

Also the lib is appropriately linked in the Input settings of the Linker and VC++ Directories settings.

Am I supposed to use different lua functions when building for x64 platform? Google doesn't show any meaningful results for this problem with linking lua functions for x64 platforms, only default ones that you need to set a directory and name of the lib file, which are set in my case.
