Trying to use the blog function in obs plugin in vs2022 (beginner to obs plugin dev)

[AndersBillLinden]

Here is what I tried:
* Start vs2022
* Click File -> new project
* Select Dynamic-Link Library (DLL) C++ project with any name
* Copy libobs and libobs-winnt folders from https://github.com/obsproject/obs-studio into project dir using windows explorer
* Right click project in Solution Explorer, click properties and in Configuration Properties -> Include Directories append ;libobs;libobs-winnt
* First "Show All Files" in solution explorer so I see the folder structure, then right click the libobs folder and "Include in project"
* In visual studio add to dllmain.cpp so it reads:

#include "pch.h"

BOOL APIENTRY DllMain( HMODULE hModule,
                       DWORD  ul_reason_for_call,
                       LPVOID lpReserved
                     )
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
    case DLL_THREAD_ATTACH:
    case DLL_THREAD_DETACH:
    case DLL_PROCESS_DETACH:
        break;
    }
    return TRUE;
}

__declspec(dllexport) bool obs_module_load(void)
{
    blog(LOG_INFO, "plugin loaded successfully");
    return true;
}

Both blog and LOG_INFO are missing here.
Why?

You are missing header files. It's best to use our plugin template for developing new plugins.

Thanks for your reply. I find no header files in the plugin template project. Will they be generated? Is there a plugin template for visual studio?

You should get a fully functioning Visual Studio project after running CMake.

CMake Error at CMakeLists.txt:24 (find_package):
By not providing "Findlibobs.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "libobs", but
CMake did not find one.

Could not find a package configuration file provided by "libobs" with any
of the following names:

libobsConfig.cmake
libobs-config.cmake

Add the installation prefix of "libobs" to CMAKE_PREFIX_PATH or set
"libobs_DIR" to a directory containing one of the above files. If "libobs"
provides a separate development package or SDK, be sure it has been
installed.

Oh, I fetched the repo as zip. Maybe there is a submodule.
