# Findspdk.cmake -- locate a system-installed SPDK via pkg-config.
#
# Paired with WITH_SYSTEM_SPDK: link a distro-provided spdk-devel instead of
# building the bundled src/spdk fork. Modelled on Finddpdk.cmake.
#
# Provides: spdk::spdk, spdk_FOUND, SPDK_INCLUDE_DIRS

find_package(PkgConfig REQUIRED QUIET)

# spdk's .so leave ISA-L symbols (crc32_iscsi, xor_gen, ...) undefined for the
# final link and don't Require isa-l in their .pc; pull it in explicitly.
