st-project.cmake will generate "\\" on windows and "/" on macos

[FengChendian]

Type: Bug Report

Describe the bug

• OS and Version: Windows 11 22H2 and Macos 13.3.1
• VS Code Version: 1.77.3
• Embedded Tools Extension Version: 0.7.0
• Target embedded device: STM32
• Other extensions : STM32 VS Code Extension

In windows, extension will produce st-project.cmake using \\. Like :

But on macos, \\ causes error in CMake.

[build] CMake Error at CMakeLists.txt:19 (add_executable):
[build]   Cannot find source file:
[build] 
[build]     Core/Src/Core\Src\freertos.c

If I replace "\\" to "/", everything is ok.

Thanks for the report! We should be able to fix this in the next release of the extension.
