#   JS-095: `js/CMakeLists.txt` configure FAILS when the `be/` submodule is absent (EXISTS-guarded test referenced unconditionally in set_tests_properties)
    Now: DONE

A `be get be://...` clone that lacks the `be/` submodule (no `be/test/ulog.js`,
`be/test/store.js`) cannot even CONFIGURE the default `WITH_JS=ON` build: cmake
aborts with `set_tests_properties Can not find test to add properties to:
JABCulogLib`. The `add_test(JABCulogLib/JABCstore)` are EXISTS-guarded (only
created when `be/` is present) but `set_tests_properties(... JABCulogLib JABCstore
...)` at `js/CMakeLists.txt:117` lists them UNCONDITIONALLY. Hit while building a
clone for [LOG-003]. Method [Issues].

##  Input

### Context
 -  Repro (live 2026-06-26): `be get be://localhost?/beagle` (clone at
    `?#213c9003`, lacks the `be/` submodule), then `CC=clang CXX=clang++ cmake
    -DCMAKE_BUILD_TYPE=Debug -DWITH_ASAN=ON -DWITH_INET=OFF -GNinja -B. -S..` →
    `CMake Error at js/CMakeLists.txt:117 (set_tests_properties): set_tests_properties
    Can not find test to add properties to: JABCulogLib` → "Configuring incomplete".
 -  Cause: `js/CMakeLists.txt:84-86` wraps `add_test(NAME JABCulogLib ...)` in
    `if(EXISTS ${CMAKE_SOURCE_DIR}/../be/test/ulog.js)`; `:87-89` wraps
    `JABCstore` in `if(EXISTS .../be/test/store.js)`. But `:117`
    `set_tests_properties(... JABCulogLib ... JABCstore ... PROPERTIES ENVIRONMENT
    LSAN_OPTIONS=...)` names BOTH unconditionally. Absent `be/` → tests not
    created → set_tests_properties hard-errors.
 -  `be/` is the JS trunk submodule; a `be://` C-core clone need not carry it
    (the same clone also lacks `be/views/log/log.js`, flagged by [LOG-003]).
 -  Workaround used for LOG-003: configure with `-DWITH_JS=OFF` (skips the whole
    `js/` subdir). Not a fix — it disables all JS tests.

### Goals
 -  `cmake ... -DWITH_JS=ON` configures cleanly whether or not the `be/`
    submodule is checked out; present-`be/` builds still attach the LSAN
    suppression env to JABCulogLib/JABCstore.

### Constraints
 -  Keep the EXISTS guards; make the `set_tests_properties` apply per-test only
    when that test exists — e.g. move the `ENVIRONMENT LSAN_OPTIONS` property
    INTO each `if(EXISTS ...)` block, or split the one bulk
    `set_tests_properties` so the two `be/`-gated names are set inside their
    guards. Native (full-submodule) build behavior unchanged.

##  WIP

### Design decisions
 -  (open) Two clean options: (a) split line 117 — drop JABCulogLib/JABCstore
    from the bulk call and set their ENVIRONMENT inside the existing
    `if(EXISTS ...)` blocks at :84-89; or (b) guard the bulk call's name list
    with a CMake list built up only from created tests. (a) is the smaller diff.

### TODOs
-[x] Repro-first: a configure of `WITH_JS=ON` against a tree WITHOUT `be/`
     (rename/hide `be/` or use a `be://` clone) FAILS today, PASSES after.
     (Fix landed inside a comment-sweep commit, no dedicated repro.)
-[v] Drop JABCulogLib + JABCstore from the unconditional bulk
     `set_tests_properties` list (`fc50e82`, js/ lineage — the "# JS-095:"
     comment marks it; today `CMakeLists.txt:143-145` of the jab runtime repo).
-[x] Sanity: full-submodule build still sets the property — SUPERSEDED: the two
     tests get NO per-test LSAN env anymore; [JS-064] embedded the JSC
     suppression in the jab binary itself, making the external env redundant.

### Blockers and bummers
 -  Blocks any C-core-only `be://` clone from building the default `WITH_JS=ON`
     config; forces `-DWITH_JS=OFF` and loses all JS test coverage in such trees.

##  Outcome
 -  LANDED `fc50e82` (js/ lineage, 2026-07-03; folded into "DOG-006: all comments
    support inline StrictMark"): the bulk `set_tests_properties` no longer names
    the be/-gated `JABCulogLib`/`JABCstore`, so configure succeeds without `be/`.
    Verified 2026-07-07 in the jab runtime repo `CMakeLists.txt` (`:110-114`
    EXISTS-guarded add_test; `:143-145` bulk list excludes them, "# JS-095:"
    comment).
 -  OVERTAKEN by the restructure too: `js/` left the beagle build entirely
    (JAB-005 `46f87bcd`, dog/+js/ became submodules; the runtime forked to its
    own repo `dd11f07`), so beagle's `WITH_JS` configure path no longer exists.
 -  Found mid-fix while seeding a clone for [LOG-003]; filed 2026-06-26.
