acassis opened a new pull request, #19755: URL: https://github.com/apache/nuttx/pull/19755
## Summary 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. ## Impact Fixes https://github.com/apache/nuttx/issues/19697 ## Testing Tested as #19697 and compiled correctly -- This is an automated message from the Apache Git Service.
