STM32CubeMX 4.26.0 break Linux Atollic 9.0.0 project

I upgraded CubeMX to 4.26.0!

Migrated my existing project to 26.

Generated source code for Atollic TrueStudio 9.0.0

When I compile with Atollic TrueStudio 9.0.0 under Ubuntu

the Post-build step: 'arm-atollic-eabi-objcopy.exe ...' failed because program not found.

Workaround:

Updating TrueStudio project setting: C/C++ Build/Setting/Build Steps/Post-build step

From:

arm-atollic-eabi-objcopy.exe

To:

arm-atollic-eabi-objcopy

Saved the day, however - The windows style program name reappears with every source code generation from CubeMX
