# NOTE: When using cpp-httplib as a subproject (e.g., via FetchContent), the zstd::libzstd target may not be visible in the parent project scope. # NOTE:
# If you encounter a "target not found" error, see https://github.com/yhirose/cpp-httplib/issues/2313 for a workaround. # zstd < 1.5.6 does not provide the CMake imported target `zstd::libzstd`.
# Older versions must be consumed via their pkg-config file.
