	Are you talking about the -I includes? They are necessary as most of the code resides outside of where the .ino file lies. (and they are all added into the Visual Studio solution so they are compiled). However, the file with the not-found #include and the ino file are in the same directory, the base directory of the project. I am not able to reproduce the same issue with a fresh project, even with the files in different projects. I think my issue comes from the fact that the path from ino -> file-with-the-library-include is a little a-typical for Arduino projects. Somehow, it seems to be covered by my board.txt with the "all" settings (at least this is my explanation right now, you probably have a better insight in how this works). So unless I restructure my project, it might not be possible to resolve this other that with my custom board.txt. Thanks for your quick messages, helping me to unterstand the issue Daniel

	I think I see. Can you give an idea of your code structure. For example:- project project\src project\src\folder1 You are saying that libraries are not auto discovered from project code located in "project\src\folder1" unless you use the "all" option?

	So my project structure looks as follows (reduced view): Code 0) solution 1) libwinston 2) libwinston.h <-- includes ../winston-teensy/winston-teensy.h via platform-define 3) winston-teensy 4) winston-teensy.ino <-- includes ../libwinston/libwinston.h 5) winston-teensy.h <-- includes <WebSockets2_Generic.h> 6) winston 7) winston-x64.cpp <-- includes ../libwinston/libwinston.h libwinston contains my application code. winston-teensy is the Visual Micro/arduino project directory with the ino file. winston is the same application for x64, also including the libwinston files. All relevant files are added to the solution in Visual Studio. As I am said, I am not sure about how the deep-scan functionality works, but maybe the issue is the winston-teensy.h being referenced via a file not in the same directory as the ino? However, I used the same setup in January 23 where the same structure was in place (with Arduino IDE 1.8 and the Visual Micro version of that time) and I did not have this problem. Is it possible to set the lib-search=all parameter via a UI control? "Super deep library search" or something?

	Thanks for the info. We are going to add a couple of comboboxes to the vMicro>general that allows nusers to controller how deep "deep search" goes. It sounds like you have a library that includes another library from code deep er than the root of the library. As you found, you do need these options at the moment because the default only searches the first level. This is because platforms such as esp32 are so slow which causes long compile times when nothing has changed. vm.preproc.lib-search.lib-in-lib=all vm.preproc.lib-search.lib-in-sketch=all We might also add a button that performs a full deep search, but for when users know they have added new libraries to their code. At other times an automatic full deep search will happen when board or defines change. It might be a better solution. As a side note, user installed libraries should be in the sketchbook\libraries folder and relative or physical paths are not really in the arduino spec. Only the headers should be in the include, for example #include <Lib1.h> The v64 and VS project property property page settings are used only for intellisense. You should never need to add any -I compiler includes. Assming you have set the "all" settings, you should find the exact same code compiles in both arduino ide and visual micro.

	Thank you. Maybe I can update my project structure accordingly. Looking forward to the new settings I was just very puzzled why my setup did not work any longer. Best Regards Daniel
