# ---- app.vrmanifest generation (Plan 03-02 — D-19) -----------------------
# Phase 10 / D-18: MICMAP_VERSION now flows from cmake/version.cmake (the SSoT
# included at root level). The prior `set(MICMAP_VERSION ${PROJECT_VERSION})`
# line is gone — MICMAP_VERSION is in cache scope here via the root include().
# Use @ONLY so only @TOKEN@ markers are substituted (prevents accidental
# ${...} expansion inside JSON values).
#
# configure_file() does not honor generator expressions in its OUTPUT path, so
# we emit to ${CMAKE_CURRENT_BINARY_DIR} and copy into the per-config runtime
# dir via a POST_BUILD step. The schema test
# (test_vrmanifest_schema) reads from ${CMAKE_RUNTIME_OUTPUT_DIRECTORY}/$<CONFIG>/
# under multi-config generators (MSBuild), so the POST_BUILD copy is the
# load-bearing step.
