Problem Description

When I create my own cmake toolchain and specify set(CMAKE_SYSTEM_NAME Linux) at the top and I run fprime-util generate <custom_arch> , things work correctly, but I get this warning:

.
.
.
-- [fpp-tools] fpp-locate-defs found at: /workspace/MyProject/fprime-venv/bin/fpp-locate-defs
-- [FPRIME] Module locations: /workspace/MyProject/fprime;/workspace/MyProject
CMake Warning at fprime/cmake/platform/platform.cmake:25 (message):
  Toolchain '<custom_arch>' should set CMAKE_SYSTEM_NAME to 'Generic' and set
  FPRIME_PLATFORM

-- Including /workspace/MyProject/fprime/cmake/platform/Linux.cmake
-- Requiring thread library

.

However, when I do what the warning asks me to do (i.e. specify CMAKE_SYSTEM_NAME as Generic and set FPRIME_PLATFORM to Linux), it throws an error doesn't generate the cache.

When running fprime-util generate <custom_arch>

CMake Generate step failed.  Build files cannot be regenerated correctly.
[ERROR] CMake erred with return code 1. Partial build cache remains. Run purge to clean-up.

Should I not be using Linux as the FPRIME_PLATFORM?

Context / Environment

Execute fprime-util version-check and share the output.

# fprime-util version-check
Operating System: Linux
CPU Architecture: riscv64
Platform: Linux-6.2.2-riscv64-with-glibc2.37
Python version: 3.11.8
CMake version: 3.28.3
Pip version: 24.0
Pip packages:
    fprime-tools==3.4.4
    fprime-gds==3.4.3
    fprime-fpp-*==2.1.0a3

How to Reproduce

1. Define a ./cmake/toolchain/<custom_arch>.cmake file and place the following at the top:

set(CMAKE_SYSTEM_NAME Generic)
set(FPRIME_PLATFORM Linux)

2. fprime-util generate <custom_arch>

Expected Behavior

fprime-util generate <custom_arch> should complete successfully.
