ci: pass EBLDR_BUILD_TESTS, not BUILD_TESTS, in the tag release job - #172
The tag-only release job in ci.yml configured with -DBUILD_TESTS=OFF. This project's option is EBLDR_BUILD_TESTS, so CMake ignored the flag with an "unused variable" warning. This PR passes the real option. It also adds a check that fails whenever a workflow passes a -D name the project doesn't declare.
The build doesn't change: EBLDR_BUILD_TESTS already defaults to OFF, and the build.ninja CMake writes is byte-identical before and after (see Testing). What changes is that the flag now does what it says, and a misspelt flag can no longer pass silently. The test job had the same misspelling, which #41 fixed (TASKS.md T-004).

Changes
.github/workflows/ci.yml:218 (release job): -DBUILD_TESTS=OFF → -DEBLDR_BUILD_TESTS=OFF. The same spelling as build-arm at line 113.
tests/unit/test_build_options_are_read.py: a third rule next to the two already there.
The rule: every -D argument of a cmake configure command in a workflow's run: script must name a variable CMakeLists.txt declares (option() or a CACHEset(), the same _declared_options() the file already uses). The three spellings CMake accepts count: -DNAME=v, -DNAME:TYPE=v and the spaced -D NAME=v.
What it reads: each workflow is parsed with PyYAML and only step run: strings are scanned. Backslash continuations are joined. Full-line and trailing # comments are stripped. The script is split into commands at &&, ||, ;, |, $(, backticks and parentheses, so a cmake inside $( … ) or a subshell is a command of its own. Leading then/do/else/elif/if/!, VAR=value assignments and env/time/sudo/nice/exec (with their options) are dropped before the program name is tested, so then cmake …, env FOO=1 cmake … and sudo -E cmake … are still read as configures.
What it does not count:cmake --build/--install/-E/-P, any other program (gcc -DNDEBUG=1, export CFLAGS="-DUSE_X=1"), and a -D inside a quoted flags value such as -DCMAKE_C_FLAGS="-DFOO=1 -O2".
Not the project's to declare: variables owned by CMake or its standard modules and toolchains are skipped by prefix: CMAKE_*, FETCHCONTENT_*, Python3_*, IDF_*.
Tests:
19 parser cases, one per shape above, including then cmake -DTYPO=1 .., env FOO=1 cmake -DTYPO=1 .., VAR=value cmake, do cmake, time cmake, sudo -E cmake, $(cmake …) and (cd x && cmake …);
4 allow-list cases;
4 negative controls, each run against the real ci.yml scripts plus one more script: -DBUILD_TESTS=OFF, a misspelt -DEBLDR_BUILD_TEST=ON, the same in spaced form, and -DEBLDR_ENABLE_SECURITY_CHECKS=ON. That option is declared only in cmake/security_checks.cmake, which CMakeLists.txt never includes, so passing it does nothing;
a check that the scan sees the flags the test job really passes.
Testing
Unit tests pass (ctest --test-dir build --output-on-failure): 36/36
Integration tests pass (not run; no integration suite touched)
Manual testing performed: the release job's configure line, before and after

Additional Notes
Not changed here:
The release job packages no bootloader. It builds the host configuration (EBLDR_BOARD defaults to none), which produces only static libraries. Its find build/release -name "*.elf" / "*.bin" then matches one file: CMake's own compiler probe CMakeFiles/<version>/CMakeDetermineCompilerABI_C.bin (see raw-configure.log). release.yml builds the real per-board firmware on the same v* tags. Whether this job should build a board, or be removed in favour of release.yml, is a maintainer decision, so it is left alone.
ci/ci_security.yml is not scanned. It is not under .github/workflows/, so GitHub never runs it. Its line 32 passes -DEBLDR_ENABLE_SECURITY_CHECKS=ON, the option the fourth negative control uses.
CMAKE_CXX_COMPILER. The test job passes -DCMAKE_CXX_COMPILER=g++-12 to a C-only project, and CMake reports that as unused too. It is CMake's own variable and harmless, so the new rule skips every CMAKE_* name, and that flag is left as it is.
Known limit: a -D placed after $(...) or after sudo -u <user> is not checked; no workflow uses either form.
Summary by Sourcery
Correct the release workflow's test option and prevent undeclared CMake flags from passing silently in CI.
Bug Fixes:
Use the declared EBLDR_BUILD_TESTS option in the release workflow so the test setting is applied correctly.
Enhancements:
Add validation that workflow CMake configure flags reference declared project options, while ignoring standard CMake and toolchain variables.
CI:
Strengthen workflow checks to detect misspelled or ineffective CMake -D arguments across workflow run scripts.
Tests:
Add coverage for parsing CMake configure commands across shell syntax variants, supported variable forms, wrapper commands, exclusions, and undeclared options.
Summary by CodeRabbit
Chores
Updated the release build configuration to use the current test-build option.
Tests
Added checks that workflow CMake options are declared project options, while standard CMake and tool-specific variables are exempt.
The release job in ci.yml configured with -DBUILD_TESTS=OFF. The project's
option is EBLDR_BUILD_TESTS, so CMake ignored the flag with an "unused
variable" warning. The test job had the same misspelling until embeddedos-org#41 (TASKS.md
T-004); this is the copy that was left behind. The build graph CMake writes is
unchanged, because EBLDR_BUILD_TESTS already defaults to OFF.
tests/unit/test_build_options_are_read.py gains a third rule: every -D a
workflow's run script passes to a cmake configure command (-DNAME=v,
-DNAME:TYPE=v or -D NAME=v) must name a variable CMakeLists.txt declares.
Variables owned by CMake or its modules (CMAKE_*, FETCHCONTENT_*, Python3_*,
IDF_*) are skipped, as are cmake --build, other programs, comments and a -D
inside a quoted flags string. A configure that follows then/do, env, time,
sudo or a VAR=value assignment, or sits inside $( ... ) or ( ... ), is
still read. It fails on the old ci.yml with
{'ci.yml': ['BUILD_TESTS']}; parser cases and negative controls cover each
of those shapes.

The release workflow now uses EBLDR_BUILD_TESTS=OFF. Unit tests scan workflow CMake configure commands and check that their defines use declared project options, with configured standard-variable prefixes excluded.
The test module parses shell commands and recognizes supported CMake configure -D forms. Parameterized tests cover shell layouts, comments, wrappers, and excluded commands or flags.
The release workflow uses EBLDR_BUILD_TESTS=OFF. Tests check workflow defines against declared options, verify configured standard-variable exclusions, and confirm that undeclared defines are detected.
The release workflow uses the declared test option, and no current workflow command was found to bypass the new check. The narrow parser limitation does not block merging.

Explanation
Issue #171 requires the release job to use the declared test option and a check to reject undeclared CMake flags in workflow commands. .github/workflows/ci.yml now passes -DEBLDR_BUILD_TESTS=OFF. The new guard scans workflow run: scripts against declarations in CMakeLists.txt. Tests cover the prior BUILD_TESTS error, misspellings, spaced -D syntax, and relevant parser forms. The current workflow scripts are covered. The guard has documented limits for uncommon shell forms, including -D after $(...) and sudo -u; the PR reports that no current workflow uses these forms.

• Pass the declared EBLDR_BUILD_TESTS option in the tag-only release job; the build remains
unchanged.
• Fail tests when workflows pass undeclared project options to CMake configure commands.
• Cover supported command forms, exclusions, and known misspellings with parser and regression
tests.
The following are alternative approaches to this PR:
1. Validate flags through CMake configure runs
➕ Tests whether CMake actually consumes supplied variables, including variables declared outside the top-level file.
➖ Requires configuring workflow variants and interpreting CMake warnings, making the guard slower and more environment-dependent.
Recommendation: Keep the lightweight source-level guard: it fits the existing build-option tests and catches this misspelling without running release builds. The trade-off is that its shell scanner recognizes supported command forms rather than executing arbitrary shell scripts.

**Quoted values hide configure flags**
When a workflow configure command has a quoted value containing `#`, a shell operator, or a shell substitution before a later `-D` argument, `_strip_shell_comment` and `_commands` process comment markers and separators without respecting shell quoting, so they truncate or split the command; the guard misses a later undeclared flag or invents a fake CMake command, and the workflow check passes or fails incorrectly.

EBLDR_BUILD_TESTSalready defaults toOFF, and thebuild.ninjaCMake writes is byte-identical before and after (see Testing). What changes is that the flag now does what it says, and a misspelt flag can no longer pass silently. The test job had the same misspelling, which #41 fixed (TASKS.md T-004).Type of Change

Not changed here:
releasejob packages no bootloader. It builds the host configuration (EBLDR_BOARDdefaults tonone), which produces only static libraries. Itsfind build/release -name "*.elf"/"*.bin"then matches one file: CMake's own compiler probeCMakeFiles/<version>/CMakeDetermineCompilerABI_C.bin(seeraw-configure.log).release.ymlbuilds the real per-board firmware on the samev*tags. Whether this job should build a board, or be removed in favour ofrelease.yml, is a maintainer decision, so it is left alone.ci/ci_security.ymlis not scanned. It is not under.github/workflows/, so GitHub never runs it. Its line 32 passes-DEBLDR_ENABLE_SECURITY_CHECKS=ON, the option the fourth negative control uses.CMAKE_CXX_COMPILER. The test job passes-DCMAKE_CXX_COMPILER=g++-12to a C-only project, and CMake reports that as unused too. It is CMake's own variable and harmless, so the new rule skips everyCMAKE_*name, and that flag is left as it is.-Dplaced after$(...)or aftersudo -u <user>is not checked; no workflow uses either form.Summary by Sourcery
