This extends information provided in the project_description.json file.
Newly added information can be used in the SBOM generating tool and
also to improve hints regarding the the component dependency issues.
Added fields
version:
This adds versioning to the project_description.json file,
so it's easy to identify if it contains the required information.
project_version:
Can be used as a version for the resulting binary e.g. `hello_world.bin`.
idf_path:
This one is probably not necessary, but it allows tools to run even without
esp-idf environment exported(e.g. export.sh).
c_compiler:
The `CMAKE_C_COMPILER` value with full path to the compiler binary. This can
be used to get information about toolchain, which was used to build the project.
common_component_reqs:
List of common components as presented in cmake's __COMPONENT_REQUIRES_COMMON
and set in tools/cmake/build.cmake:__build_init().
build_component_info:
Detailed information about components used during build. It's a
dictionary with the component name as a key and each component has
a dictionary with detailed information. Following is an example for
the efuse component.
"efuse": {
"alias": "idf::efuse",
"target": "___idf_efuse",

Currently make_json_list() returns '[ "" ]' for empty cmake list. Fix this
so empty json list is returned instead.

`__COMPONENT_TARGETS` is evaluated very early when components and
component directories are added to the build, which means that all
components (including the ones which are in EXCLUDE_COMPONENTS) have
a build system target defined. The component manager was given the
list of all known components (derived from the list of targets), not
the list of components after EXCLUDE_COMPONENTS were processed.
Because of that, EXCLUDE_COMPONENTS didn't effectively exclude the
component from the consideration of the component manager.
Defining CMake variables from the command-line or from another CMake project,
such as `-DCMAKE_C_FLAGS= -DCMAKE_CXX_FLAGS=`, caused a link failure as ESP
CMake was unable to set its proper compilation flags.
Additional CMake compiler flags can now be provided by another project.
* Closes https://github.com/espressif/esp-idf/issues/7507
This feature was added when we thought that target components might be
added out of IDF tree. That never became possible, and with recent
changes in IDF architecture it is unlikely that this feature will be
necessary any time soon. Remove it, simplifying the code.
This is an experimental feature intended at the moment for ESP-IDF
developers only.
If IDF_TOOLCHAIN=clang environment variable or CMake variable is set,
use toolchain-clang-esp32xx.cmake instead of toolchain-esp32xx.cmake.
These changes aren't sufficient to actually build any IDF project with
clang; subsequent commits add a few workarounds required to do this.
Toolchain files are added for esp32 and esp32s2, which are the targets
supported in our llvm-project fork at the moment.
CMake sorts result of file(GLOB) command since version 3.6.0:
https://gitlab.kitware.com/cmake/cmake/-/commit/edcccde7d
Since ESP-IDF sets cmake_minimum_required version to 3.5, and version
3.5.1 is used in CI, sort file lists obtained from file(GLOB)
manually.
This helps obtain reproducible order of libraries passed to the linker
and to ldgen.
