Hello, Im trying to setup ruby-imgui.. and I have glfw compiled and ready. I also have cimgui ready. I go to do ruby test_glfw_opengl2.rb and it says `rescue in block in dlload': can't load C:/Users/user/ruby-imgui/sample/GLFW3.dll. GLFW3.dll is in the sample folder.. what could be the problem?

Hello!

I've tried this wrapper and it is awesome! Thank you very much for it! Although, I could not bundle this 'gem' into my rubyc compilled app.exe, since ffi is not a standard gem and It fails at the compillation due to ffi is a C ext gem (see rubyc...). Never mind, in short, I can only use fiddle but not ffi.... 😥.
I saw that you've already dealt with both tool (fiddle, and ffi), and I would be so curious about whether there are any chance rewriting ImGui wrapper in fiddle? I've already solved the string pointers using fiddle in imgui-opengl.rb and imgui-glfw.rb, but - logically - I'm struggling with the imgui.rb conversion proccess.... Do you have any suggestion? I would be intrested in how to pass a struct as a struck's element in fiddle. (Like what you did with the FFI..by_value function)

This and your nuklear binding would be really useful packaged as gems instead of stand-alone projects so that they could be used like any other gui library gem.

Hello.
The setup for opengl uses hardcoded paths on linux which are not "standard" on all distributions sadly, most have recently switched to abolishing the subdirectories like x86_64-linux-gnu or some have their libs installed themselves in /usr/local/lib.
The default library paths can be found via ld --verbose | grep -o SEARCH_DIR[^\;]* for example. Ideally it would try all of them sequentially and use the first one it finds. I am sadly not aware of any Ruby way to query that.
The only thing i can think of is doing something like:
Dir.glob("/usr/l*/**/libglfw.so") for example to get the actual path to an existing libglfw.so
