Getting two different build logs when running same command locally and on CI/CD

[ashutoshpandey-eaton]

Using zephyr 3.2.0 and sdk version: zephyr-sdk-0.15.2 and windows (locally and in CI/CD)

PROBLEM: When building using the same command with the same project(west build -b nucleo_h743zi -p ) locally and on CI/CD, getting two different build logs

Description
Build_logs_CI_CD.txt
Build_logs_running_locally.txt

When building locally (logs attached)
It picks "my_project/src" files first for the compilation (check:[8/363] in Build_logs_running_locally.txt)
When building on CI/CD(logs attached)
which uses the same zephyr version and SDK on Windows it picks "zephyr/arch" files first for the compilation (check:[8/363]in Build_logs_CI_CD.txt)

1. What can be the possible root cause for this, why is this behaving differently??
2. Why on CI/CD logs Zephyr build system not picking "my_project/src" files first for the compilation instead of that it is picking "zephyr/arch files" first for compilation?
3. Who is deciding the compilation sequence?
