+- update to 1.8.4:
+ * Add ALEMBIC_DEBUG_WARNINGS_AS_ERRORS to control the build in debug mode.
+ * It is set to ON by default to preserve the current behavior.
+ * Use add_compile_options instead of the older add_definitions. (PR371)
+ * Fix the include dirs for AbcCoreHDF5 tests. (PR382)
+ * Fix issue hinted at in Issue 223: use PROJECT_SOURCE_DIR instead of
+ * CMAKE_SOURCE_DIR when embedding Alembic within another CMake project.
(PR393)
+ * On Windows _BitScanForward64 is only available when _WIN64 is defined.
+ * When it is not, fall back on using _BitScanForward. (PR 373)
+ * Fuzzer issue 49213 turned up some new malformed MetaData memory problems.
+ * Indexed MetaData on the write side only allows 254 (plus the default empty
one)
+ * small (up to 256 bytes), we now throw if we encounter malformed MetaData.
+ * We were also allowing empty property and object names through on the read
side
+ * even though the writer forbids this.
+ * Finally integrate a couple of tests flagged by Taotao Gu's local fuzzer.
+ * (PR391 and PR397)
+ * Fuzzer issue 52939 showed that with certain malformed MetaData the pair
+ * separator should NOT occur before the assign separator. (PR396)
+ * N2f and N2d properties were not being correctly bound.(PR390)
