# FindZstd
# ---------
#
# Try to locate the Zstd library.
# If found, this will define the following variables:
#
# ``ZSTD_FOUND``
#     True if the zstd library is available
# ``ZSTD_INCLUDE_DIRS``
#     The zstd include directories
# ``ZSTD_LIBRARIES``
#     The zstd libraries for linking
#
# If ``ZSTD_FOUND`` is TRUE, it will also define the following
# imported target:
#
# ``ZSTD::ZSTD``
#     The zstd library
