Generating incorrect object paths

[ad7718]

I use default config as reference to build simple stm32f103 HAL blink project. My system is Windows 8.1, VS code version is 1.26.1.

CrossBuild generates incorrect object paths, for example:
"build .build\Debug\obj\C:\Users\Username\Desktop\vscode_stm32_blink\Src\main.c.o: CC C:/Users/Username/Desktop/vscode_stm32_blink/Src/main.c"
