If you install a library they are located in mydocuments/arduino/libraries. Delete a lib folder and that is all that is required. Click rescan or restart the ide.

If you have used the "create shared lib project" or "toggle hidden files" then manually remove the short cut from your project solution by selecting it and right click delete.

Hmm, I have another question:
Why I have to add the sources in ..espressif\esp32\libraries folders to each project? I thought thats enough if I do it ones in vMicro. Whats the reason or is there any other way to add it permantly for all ESP32 projects?

Thanks

Hey, yes, I understand BUT:
1. I have GIT clone the https://github.com/espressif/arduino-esp32. There is a "libraries" folder in there...which is official ... but vMicro does not find the libraries automatically ... only if I add for each project manually via "Add Library - Build-in".
2. I have configured my project for "M5Stack-Core-ESP32".
3. There is another problem with SD library. vMicro does not show me the SD library from ESP32 in "Add Library - Build-in". There seems to be a conflict with the custom SD library for ESP8266 which I have installed in ..projects\libraries\SD\ path. Only if I remove or rename that path vMicro shows me SD(ESP32) in "Add Library - Build-in".

So, it seems to me two bugs in vMicro. 
1. it cannot resolve the libraries path from ESp32 git clone
2. it has problems when build-in and user libs ... in different directories .. have the same name. 

Again. ArduinoIDE has not the problems. All works fine. 
This is my first day with vMicro.

Thanks for help in advance

Modify 1: Ahh, and yes I have payed the pro version today...but different email account.

Modify 2:My directory structure is as following:
..\projects\
          project1
          project2
          ...
          hardware\
                 espressif\esp32\ ... (git clone of arduino-esp32)
          libraries\
              BME280\
              ESPAsyncTCP\
              ...
              SD\
              ...
              WifiManager\
              (that are all libraries installed by Arduino library manager, for esp8266 and also esp32 .. such as M5Stack)

Thanks.

Super! Works great so far.
I cleaned project folder from Visual Studio files and reimported. All libs have been found automatically.
Great work!

Interrestingly, I get other error from Intellisense:
register uint32_t *sp asm("a1");

"asm" is not recognized but compiles fine.

Any idea?
