Core caching fails when custom build path on different drive from system temporary folder

[per1234]

Describe the problem

Under the following conditions:

• A custom build path is set via the --build-path flag.
• The build path is on a different drive from the system temporary folder.

core caching fails:

Couldn't deeply cache core build: Rel: can't make E:\build-path relative to C:\Users\per\AppData\Local\Temp\arduino\cores

To reproduce

$ arduino-cli version
arduino-cli.exe  Version: git-snapshot Commit: 2c2a5cc6 Date: 2023-04-24T05:04:04Z

$ arduino-cli sketch new "e:/FooSketch"  # The sketch path must be on the same drive as the build path due to arduino/arduino-cli#2156
Sketch created in: e:\FooSketch

$ arduino-cli compile --build-path "e:/build-path" --fqbn arduino:avr:uno "e:/FooSketch"
Couldn't deeply cache core build: Rel: can't make e:\build-path relative to C:\Users\per\AppData\Local\Temp\arduino\cores
Running normal build of the core...
Sketch uses 444 bytes (1%) of program storage space. Maximum is 32256 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

Used platform Version Path
arduino:avr   1.8.6   C:\Users\per\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.8.6

Expected behavior

Core caching to be done regardless of build path location.

Arduino CLI version

2c2a5cc

Operating system

Windows

Operating system version

11

Additional context

I was not able to reproduce the fault on Linux or macOS
