Some of our FindWrap scripts try to call find_package() once or more to find a system package, and then fallback to a different source in case if not found. The side effect of this is that find_package() will append not found packages to the global PACKAGES_NOT_FOUND property. FeatureSummary feature_summary() will then list these as not found, creating confusion. For example while FindWrapSystemPCRE2 might be found, PCRE2 found will be shown as not found, because we found the package via PkgConfig instead of cmake Config file. Manually remove these packages from the PACKAGES_NOT_FOUND property in some of our Find scripts, to avoid the confusion.

# The zstd include directories

# The zstd libraries for linking

# If ``WrapZSTD_FOUND`` is TRUE, it will also define the following
