 The code paths m7 (Intel® SSE3) and w7 (Intel® SSE2) are deprecated and will be removed from the merged build of Intel® Cryptography Primitives Library in the future releases. 1cpu headers are still available for all code paths. These branches can also be built as 1cpu libraries if specified in the platform list, e.g. `-DMERGED_BLD:BOOL=off -DPLATFORM_LIST=s8;e9`.

Users should be aware that the installation path may not match the expected location for standalone builds. This issue will be fixed in the next major release.
