cpp-linter complains about gtest headers

What events trigger your workflow?

on:
  pull_request:
    types: [opened, reopened, synchronize, ready_for_review]
    paths:
      - '**.cpp'
      - '**.hpp'

What OS does your workflow use?

runs-on: ubuntu-latest

How is cpp-linter-action configured?

- uses: cpp-linter/cpp-linter-action@v2
        id: linter
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        with:
          style: 'file'  # Use .clang-format config file
          tidy-checks: '' # Use .clang-tidy config file
          # only 'update' a single comment in a pull request thread.
          thread-comments: ${{ github.event_name == 'pull_request' && 'update' }}

What was the unexpected behavior?

Workflow fails with:

'gtest/gtest.h' file not found

One solution is to ignore the files, but then I lose the check.

Is there a way to fix the issue? Should I fetch dependencies in a previous step?

I'm afraid we need a little more detail.

So, I'm assuming the 'gtest/gtest.h' file not found complaint is coming from the clang-tidy output.

Warning

Without a compilation database, clang-tidy cannot find third-party source files.

Use a compilation database

If you can generate a compilation database using your project's build system, then it is highly recommended to specify the path to the compilation database using our database input option.

I don't know what exact build system you are using, but CMake can do this easily using their builtin variable CMAKE_EXPORT_COMPILE_COMMANDS.

BTW, thread-comments do not work on PRs from a fork of the base repo. For example, thread-comment will fail for cameriere-di-rete/webserv#96.

This is a limitation set by GitHub. We cannot workaround it. I can suggest using step-summary instead.
