CMake on GitHub Action with Googletest - c

Question

Introduction
Currently, I'm working on a C project with CMake and Googletest.
My project is on a GitHub repo.
Why I execute the test on my local machine I use this command: cmake -B ./build -DCMAKE_BUILD_TYPE=Release. It works.
#MathieuSoysal ➜ /workspaces/Piscine-42 (main) $cmake -B ./build -DCMAKE_BUILD_TYPE=Release
-- Configuring done
-- Generating done
-- Build files have been written to: /workspaces/Piscine-42/build
Problem
And I'm trying to execute it on GitHub Actions. But it does not work.
The Log

cmake -B /home/runner/work/Piscine-42/Piscine-42/build -DCMAKE_BUILD_TYPE=Release

Question
Does someone know how we can execute this command cmake -B /home/runner/work/Piscine-42/Piscine-42/build -DCMAKE_BUILD_TYPE=Release on GitHub Actions with a linked GitHub repo?
