Alexey Edelev a1ce164d74 CMake: Make zstd config-based lookup quiet
Make zstd config based lookup quiet and check for version variable
as required for ZSTD target.

Add IMPORTED_LOCATION by default for pkg-config based search.
Expect that select_library_configurations will set correct value
for ZSTD_LIBRARY.

Fixes: QTBUG-88091
Change-Id: Ia5079154ce4fc4eefbc0931317219b5ca0f3f82f

# 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
