Linker Errors when Building Assimp with Premake

Question

I'm implementing assimp 5.0.1 in an engine and I can't get to link it, I guess it's because of the way of including it, but I don't know what it is I'm doing wrong.

I'm in Windows, working with Visual Studio 2019 (C++) and the steps I took were building assimp with cmake as states in the documentation and copied the folders 'code/' 'contrib/' and 'include/' in the project, inside an 'Assimp' folder. With this, I made a premake file to build it within the project of the engine (I'm using premake5 as a generator).

The problem is that I'm getting 5 linker errors. I assume I'm not including some needed file in the premake. The linker errors are the next ones:

Including the files that contain the functions giving linker errors gives even more linker issues that I cannot solve by keep adding or including files, so I don't know exactly how to proceed.

In the premake file (copied below), if I, for instance, comment some definition like "ASSIMP_BUILD_NO_IFC_IMPORTER", it will trigger more linker errors (in this case for IFC functions), that's why I guess there's some wrong inclusion or something. Does anyone knows what it can be wrong? Would it be so helpful because I'm really lost, I've been with this like a week.

The premake file I'm using is the next:

project 'Assimp'
    kind 'StaticLib'
    language "C++"
    cppdialect "C++17"
    staticruntime "On"

    targetdir ("bin/" .. outputdir .. "/%{prj.name}")
    objdir ("bin-int/" .. outputdir .. "/%{prj.name}")
