gtest.h": No such file or directory

[SoftwareQualityLabPirklbauer]

Hello,
I am trying to use gtest inside VisualCode using the gtest-adapter, but I am struggeling while "using" the header file gtest.h.

What I have done so far:

• Download gtest from Github and copied into the working directory
• Installed C/C++ and GoogleTest Adapter in Visual Code
• Configured the compiler and include paths in C/C++ Configurations
• Wrote a small helloworld.cpp that can be built and run

As soon as I include "#include "gtest/gtest.h" I am getting the following error code:
fatal error C1083: Datei (Include) kann nicht geöffnet werden: "gtest/gtest.h": No such file or directory
The terminal process terminated with exit code: 1

Maybe someone can give me a hint what I am doing wrong?!

Best regards
Mario
