How to resolve LNK2001 in c++ projects

I have two projects, the first one is a dynamic library project, lets say Log project, and there is a file:
Log.h

#pragma once
#include "Core.h"
#include "spdlog/spdlog.h"

#include <memory>

namespace Prunus{
	class __declspec(dllexport) Log
	{
	public:
		static void Init();

		inline static std::shared_ptr<spdlog::logger>& GetCoreLogger() { return s_CoreLogger; }
		inline static std::shared_ptr<spdlog::logger>& GetClientLogger() { return s_ClientLogger; }
		static std::shared_ptr<spdlog::logger> s_CoreLogger;
		static std::shared_ptr<spdlog::logger> s_ClientLogger;
	};
}

while in Log.cpp, it is:

#include "Log.h"
#include "spdlog/sinks/stdout_color_sinks.h"

namespace Prunus {
	std::shared_ptr<spdlog::logger> Log::s_CoreLogger;
	std::shared_ptr<spdlog::logger> Log::s_ClientLogger;

	void Log::Init() {
		spdlog::set_pattern("%^[%T] %n: %v%$");
		s_CoreLogger = spdlog::stdout_color_mt("PRUNUS");
		s_CoreLogger->set_level(spdlog::level::trace);
		s_ClientLogger = spdlog::stdout_color_mt("APP");
		s_ClientLogger->set_level(spdlog::level::trace);
	}
}

And I tried to invoke the Log::Init() in Log project it self, it can work.
But when I reference it in another project which references on Log project, it throws error like:

Severity	Code	Description	Project	File	Line	Suppression State
Error	LNK2001	unresolved external symbol "public: static class std::shared_ptr<class spdlog::logger> Prunus::Log::s_CoreLogger" (?s_CoreLogger@Log@Prunus@@2V?$shared_ptr@Vlogger@spdlog@@@std@@A)	Sandbox	F:\code\Prunus\Prunus\Sandbox\SandboxApplication.obj	1	

Not sure whether there are additional settings I missed in visual studio 2022

I tried to use the Log::Init() inside the Log project, it can work, but it can not while referencing outside the project. What I want is to reference it outside the Log project.

Do not export an entire class, especially if it contains static variables.

Separate function declaration from definition.

namespace Prunus {
    class   Log
    {
    public:
        __declspec(dllexport) static void Init();
        __declspec(dllexport)   inline static std::shared_ptr<spdlog::logger>& GetCoreLogger();
        __declspec(dllexport)   inline static std::shared_ptr<spdlog::logger>& GetClientLogger();

    private:
        static std::shared_ptr<spdlog::logger> s_CoreLogger;
        static std::shared_ptr<spdlog::logger> s_ClientLogger;
    };
}

.cpp

namespace Prunus {
    std::shared_ptr<spdlog::logger> Log::s_CoreLogger;
    std::shared_ptr<spdlog::logger> Log::s_ClientLogger;

    
        void Log::Init() {
          
           ...
           ...
        }

        inline   std::shared_ptr<spdlog::logger>& Log::GetCoreLogger() { return Log::s_CoreLogger; }
        inline   std::shared_ptr<spdlog::logger>& Log::GetClientLogger() { return Log::s_CoreLogger; }
   
}
