• A clear and concise description of what the bug is:

I followed this article to bootstrap my dev environment with vcpkg: https://devblogs.microsoft.com/cppblog/vcpkg-artifacts First I tried to build the example project all in VS Code with the vcpkg environment activated like described in the article and this worked fine. Then I changed the extension of main.c to main.cpp and I made a few C++ compatibility changes to the project. You can find the changes in my fork of the getting-started repo (https://github.com/Sn1cket/getting-started/tree/build_with_cpp) In this state I am able to build the project when I run the following commands in a terminal:

vpckg activate
cmake --preset arm-gcc-cortex-m4
cmake --build --preset arm-gcc-cortex-m4

The problem starts when I try to do the same in VS Code. I am getting the following error when compiling the main.cpp file:

It seems like the compiler include paths don't get resolved properly in the VS Code vcpkg environment.

To Reproduce Steps to reproduce the behavior:

1. Clone this repository https://github.com/Sn1cket/getting-started/tree/build_with_cpp
2. Open MXChip/AZ3166/AZ3166.code-workspace in VS Code
3. Activate the vcpkg environment
4. Open the terminal in VS Code
5. Run cmake --preset arm-gcc-cortex-m4 && cmake --build --preset arm-gcc-cortex-m4
6. See error

Expected behavior I expect the build to finish like outside of the terminal

This looks suspiciously similar to #37. Can you try switching to the pre-release channel and using the new vcpkg.storageLocation setting (as described in this comment) to see if this is a long path issue? That setting should be available in on the official channel in the next few days once we ship a new official release.

[Sn1cket]

I tested the version on the pre-release channel and the problem is fixed when using a different location than the default. So it seems to be a long path issue. Thanks for your help!

[benmcmorran]

Great! Marking as fixed pending release.

[benmcmorran]

The vcpkg.storageLocation setting is now available in the official 0.7.0 release.
