Frantisek Hrbata 1fe41c4521 feat(cmakev2/compat): add idf_component_optional_requires function
Add the specified component as a dependency only if it is included in
the build. This functions the same way as in cmakev1, but it uses
generator expressions because cmake2 does not maintain the
BUILD_COMPONENTS build property, which would list all components
included in the build.

Frantisek Hrbata e248b36676 feat(cmakev2/kconfig): use cmakev2 specific config_buildv2.env.in
The current config.env.in template cannot be easily extended and shared
between cmakev1 and cmakev2. Although the root Kconfig is shared and
sources COMPONENT_KCONFIGS_EXCLUDED_SOURCE_FILE and
COMPONENT_KCONFIGS_PROJBUILD_EXCLUDED_SOURCE_FILE, these environment
variables cannot be set to empty strings. This issue arises unless we
also adjust cmakev1 and esp-docs, which use prepare_kconfig_files.py, to
properly set COMPONENT_KCONFIGS_EXCLUDED_SOURCE_FILE and
COMPONENT_KCONFIGS_PROJBUILD_EXCLUDED_SOURCE_FILE.

If an environment variable is set to an empty string and sourced in
Kconfig, kconfgen will expand the variable with expandvars(), resulting
in an empty value. This expanded variable is then appended to the root
Kconfig or the currently processed Kconfig directory path, depending on
whether osource or orsource is used, and passed to iglob. The iglog will
return the directory as a result, and when Kconfig attempts to open the
file, it will encounter an error because it is a directory.

To resolve this issue and enable sharing of the root Kconfig file, a new
config_buildv2.env.in template has been added, which includes
environment variables for the excluded components.

For cmakev1, kconfgen will encounter the osource command for
COMPONENT_KCONFIGS_EXCLUDED_SOURCE_FILE. Since this variable is not
defined in config.env.in, expandvars() will return the environment
variable name instead of expanding it, and iglob will not match
anything. Because osource is used for excluded components, the
non-existent file for osource will be skipped.

Frantisek Hrbata 70f5366408 feat(cmakev2/project): move all project-related items into project.cmake
The current approach involves transparently calling __init_build within
idf_build_library and performing all post-project() initialization
there. The issue with this method is that project_include.cmake files
also need to be included during post-project() initialization, but they
should be included in the global scope. This cannot be achieved within
the __init_build function unless it is converted into a macro. Although
using a macro is a potential solution, it risks causing global scope
pollution. Another complication is the location where project() can be
invoked; it must be explicitly[1] stated in the project's
CMakeLists.txt.  This requirement conflicts with our intention to wrap
it within the idf_project_default helper. Given these challenges, it
makes sense to introduce an explicit idf_project_init macro, where all
post-project() initialization occurs, including the inclusion of
project_include.cmake files. While we can still encapsulate this within
idf_project_default, for the plumbing commands (idf_build_library,
idf_build_executable, ...), it will need to be explicitly called after
the project() invocation.

Usage for default project:

cmake_minimum_required(VERSION 3.22)
include($ENV{IDF_PATH}/tools/cmakev2/idf.cmake)
project()
idf_project_default()

Usage for plumbing commands:

cmake_minimum_required(VERSION 3.22)
include($ENV{IDF_PATH}/tools/cmakev2/idf.cmake)
project()
idf_project_init()
idf_build_library()
...

The IDF build system v2 should be backward compatible with IDF build
system v1 in most situations. Therefore, it makes sense to reuse the
existing v1 tests and run them for v2 as well. This approach will help
ensure that v2 maintains backward compatibility. Introduce a new
--buildv2 option, which switches the existing tests to use the newly
added buildv2_test_app for v2. The goal is to enable the existing v1
tests incrementally in CI as the v2 implementation progresses.

Frantisek Hrbata 82e295ac6f fix(cmakev2/idf): fix IDF_TARGET initialization
Currently, the target consistency check with sdkconfig is performed even
if sdkconfig is not present, by comparing the selected target with the
target defined in sdkconfig.defaults. This results in an inconsistency
report when a different target is set in the IDF_TARGET environment
or cmake variable compared to sdkconfig.defaults. The behavior in
cmakev1 is to prioritize IDF_TARGET and ignore values in
sdkconfig.defaults. Perform the consistency check only if the
sdkconfig file exists.

Additionally, skip this consistency check if a set-target action is
taking place, as the old target in sdkconfig is being replaced with a
new value anyway.

Frantisek Hrbata 5bdcfc4a5b fix(test_build_system): pop SDKCONFIG_DEFAULTS from the environment
The test for guessing the target from the SDKCONFIG_DEFAULTS environment
variable is not cleaning up after itself, leaving the SDKCONFIG_DEFAULTS
environment variable set. The subsequent test performs target guessing
from SDKCONFIG_DEFAULTS passed to cmake with the -D option. The
SDKCONFIG_DEFAULTS environment variable should take precedence over the
SDKCONFIG_DEFAULTS cmake variable. This is correctly handled in cmakev2
, but in cmakev1, the SDKCONFIG_DEFAULTS cmake variable is used even if
the SDKCONFIG_DEFAULTS environment variable is set. This appears to be a
bug or at least an inconsistency in cmakev1.
