Unable to build project presumably due to missing repository files

[DeBoots]

While trying to build a project, I am faced with the following error:

 No rule to make target 'C:/Users/USERNAME/STM32Cube/Repository/Packs/ARM/CMSIS/5.6.0/CMSIS/DSP/Source/BasicMathFunctions/BasicMathFunctions.c', needed by 'Middlewares/CMSIS/CMSIS/DSP/Source/BasicMathFunctions.o'.

Understandably, I would need to change the C drive directory to match my computer. Where my issue comes in is that I am missing repository files. The only subfolder within the "Packs" folder is "STMicroelectronics". Is there a place to download these missing packs?

Welcome, @DeBoots​, to the community!

The best way to install the ARM package is using the CubeMX Package Manager:

• CubeMX > Help > Manage embedded software packages
• Tab ARM > open CMSIS
• Select the most recent CMSIS version, currently 5.6.0
• Install Now

Please let us know if it helps.
