Getting this error make: *** No rule to make target 'RCS/../', needed by '../'. Stop.
Figured out that there is an error in the new STM32CubeMX (V5.5) tool that it does not generate the linker script file(maybe because of anti-virus tool deleting that file), so that is why it is not able to find the required path. To solve this problem I actually installed the SMT32CubeMX as a plugin to the Systems Workbench IDE and then was able to generate the required files and compile the project correctly.
