+          # which CMake 3.31 does not recognise as a valid generator.
+          #
+          # The VS generator is multi-config and places build outputs under bin/<CONFIG>/
+          # (e.g. bin/Release/). Ninja is single-config and places outputs directly under bin/.
+          #
+          # master's test/CMakeLists.txt still contains hardcoded bin/$<CONFIG>/ paths in its
+          # CTest ENVIRONMENT properties (e.g. bin/Release/ze_null_test1.dll). This PR fixes
+          # those paths to use $<TARGET_FILE_DIR:ze_null_test1>/ which is generator-agnostic,
+          # but until that fix lands on master the n-1 build (which checks out master for the
+          # static loader) will fail to find the DLLs.
+          #
+          # This junction makes bin/Release/ point to bin/ so the old hardcoded paths resolve
+          # correctly. Once the fix is on master, Ninja will place DLLs in bin/ and the CTest
+          # properties will resolve directly there — this junction will never be traversed and
