cmake(bugfix):Synchronize the compilation differences between CMake and Makefile in nuttx repo

[xuxin930]

Summary

sync CMake missing sources

There are differences between the current CMake base and Makefile.
This patch synchronizes the differences between modules
so that the CMake compilation content should be consistent with the Makefile.

Impact

[arm ach, fs, sched, mm , libc, drivers]

Testing

all CI build

[nuttxpr]

[Experimental Bot, please feedback here]

Yes, but with minor improvements:

Meets Requirements:

• Summary: Clearly states the "why" (CMake/Makefile discrepancy), "what" (synchronizing modules), and "how" (patch for consistency).
• Impact: Lists affected areas, which is helpful.
• Testing: States "all CI builds" pass, indicating thoroughness.

Suggested Improvements:

• Impact:
  • Be more specific. Instead of just listing areas, briefly describe the impact within each. E.g., "fs: Adds missing source files for X feature."
  • Address ALL impact points. Even if it's "NO", explicitly state it for clarity (especially security, compatibility, etc.).
• Testing:
  • While "all CI builds" is good, a few specific examples of before/after log snippets would add strong evidence. Choose ones demonstrating the problem being solved.

Overall: Good start! Adding the specifics mentioned above will make this PR review much smoother.

hi @simbit18 It seems that there is a bash command line limitation issue under msys2
Could you help take a look?

Hi @xuxin930 Sure now I try.

I tried this PR locally

Cmake
The problem does not occur when building NuttX only with Cmake.

Cmake+Ninja
The problem occurs when building NuttX with Cmake+Ninja.

/bin/sh: line 1: /home/bit/nuttxnew/tools/gcc-arm-none-eabi/bin/arm-none-eabi-ar: Argument list too long
[813/1026] Building C object mm/CMakeFiles/mm.dir/umm_heap/umm_malloc_size.c.obj
ninja: build stopped: subcommand failed.

It is certainly related to the fact that Windows has a limit of 8192 characters for command line arguments.

This does not seem an easy error to solve!!!

Should we disable CMAKE + Ninja for Msys2 while waiting for a solution?

Should we disable CMAKE + Ninja for Msys2 while waiting for a solution?

@simbit18 nice catch!
We split the ar step here, but it seems that it only works for the default generator, not the ninja generator.
I agree that disable the ninja generator in the msys2 environment.

@xuxin930 I will be away for a few days so if you decide to disable Cmake + Ninja for Msys2 just remove -N

on build.yml for Nuttx

nuttx/.github/workflows/build.yml

@simbit18 sure, thanks for your suggestion.
