I want to use custom toolchains from a different path than

C:\Users\USER\AppData\Local\Arduino15\packages\esp32\hardware\esp32

My toolchains for esp32 are located here.

G:\Documents\Visual Studio 2019\Arduino\hardware\espressif\esp32\tools\xtensa-esp32-elf\bin

I did install it there because the documentation from Arduino-esp describes this to install it there via github because I forked it.

The shetch can find libraries, but when I start a project GCC and GNU are not taged on creating one.

Within libraries I can not #include other libraries, only windows library that I don't need. This is the mesage I get in the library project...

File 'Arduino.h' not found in current source file's directory or in build system paths.

Also the visual micro menu isn't collaps when I start a library project.

Still don't have the namespace of the field in the .cpp of HTTPClient http; declarated in the .h file. The variables are found...

I should end up with http.begin in .cpp ... but the begin doesn't show up.

If I go from the .cpp tot the hearder file and open the #included library, than I can not open it.

If I go form the shetch to the header file and open de #include than it opens..

I can only open the header file from the .cpp file.

The boards are included into my project even when installed in to a different folder by using the manual of Arduino-Esp for installing it with github extension. The toolchain just don't show up when creating a project, but it works...

I just found the solution by watching your youtube video over and over again. It cost me a weekend to find out. But now I found it! You should make a page on your website and place this in bold. Evry time I created a library I had this issue into the cpp.

Create shared project when including Libraries. (see picture)

I was affraid by including the libraries with the menu bar that the library has been copied to the folder and therefore not could been pushed to git. 

In the library poject it is an other story because you can not add your library in you library. So it is better to edit the library in to the project and save it. Then editing the library with intellisense just works fine in the shetch project and the .cpp and now it is compiling.
