This change fixes NuttX’s CMake support when NuttX is embedded
in another project via add_subdirectory(). CMake’s CMAKE_SOURCE_DIR
and CMAKE_BINARY_DIR refer to the outermost project, causing NuttX
to access its .config, generated files, host tools, and build artifacts
in the parent project’s directories. The fix introduces NUTTX_DIR and
NUTTX_BINARY_DIR, based on CMAKE_CURRENT_SOURCE_DIR and
CMAKE_CURRENT_BINARY_DIR, and consistently uses them for NuttX
self-references while preserving existing standalone builds. It fixes
the Kconfig initialization failure reported in #19697 and allows an
embedded sim:nsh build to configure, build, and boot successfully.
The change affects only the CMake build system (not Make or Kconfig
defaults), requires the corresponding nuttx-apps change, and does not
extend add_subdirectory() support to cross-compiled non-sim boards due
to CMake’s toolchain-file limitation.
Fixes#19697.

Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

Currently only FLAT mode development can enjoy cmake build system. This
patch tries to add initial kernel mode support. It can build NuttX kernel
and libproxies.a, the latter will be further checked though.
This can already help to build an AMP remote node image as it can share
userland apps living in the AMP master node.
Major changes:
- in top folder:
- CMakeLists.txt adjust for KERNEL mode, separate from PROTECTED mode.
- in `syscall`:
- CMakeLists.txt add mksyscall target for stubs/proxies generation
- in `syscall/stubs`:
- CMakeLists.txt use dependency to mksyscall
- in `syscall/proxies`:
- CMakeLists.txt use dependency to mksyscall
- in `arch`:
- CMakeLists.txt separate KERNEL from PROTECTED mode.
- in `arch/risc-v/src`:
- CMakeLists.txt separate from PROTECTED mode, add sub folders.
- in `arch/risc-v/common`:
- CMakeLists.txt add sources and sub-folders for KERNEL mode.
- in `arch/risc-v/k230`:
- CMakeLists.txt add sources for KERNEL mode.
- in `boards/risc-v/k230/canmv230/src`:
- CMakeLists.txt adjust k230 specific scripts for kernel mode.
New additions:
- in `arch/risc-v/src/nuttsbi/` add CMakeLists.txt
- in `arch/risc-v/src/common/supervisor/` add CMakeLists.txt

1. Update all CMakeLists.txt to adapt to new layout
2. Fix cmake build break
3. Update all new file license
4. Fully compatible with current compilation environment(use configure.sh or cmake as you choose)
------------------
How to test
From within nuttx/. Configure:
cmake -B build -DBOARD_CONFIG=sim/nsh -GNinja
cmake -B build -DBOARD_CONFIG=sim:nsh -GNinja
cmake -B build -DBOARD_CONFIG=sabre-6quad/smp -GNinja
cmake -B build -DBOARD_CONFIG=lm3s6965-ek/qemu-flat -GNinja
(or full path in custom board) :
cmake -B build -DBOARD_CONFIG=$PWD/boards/sim/sim/sim/configs/nsh -GNinja
This uses ninja generator (install with sudo apt install ninja-build). To build:
$ cmake --build build
menuconfig:
$ cmake --build build -t menuconfig
--------------------------
2. cmake/build: reformat the cmake style by cmake-format
https://github.com/cheshirekow/cmake_format
$ pip install cmakelang
$ for i in `find -name CMakeLists.txt`;do cmake-format $i -o $i;done
$ for i in `find -name *\.cmake`;do cmake-format $i -o $i;done
