# We cannot use the imported target here, because cmake will introduce an target_link_libraries(leveldb SHLWAPI::shlwapi)
# -isystem compilation directive and cause the build to fail with MinGw.
# This comes from a couple cmake bugs:
# - https://gitlab.kitware.com/cmake/cmake/issues/16291
# - https://gitlab.kitware.com/cmake/cmake/issues/19095
# These issues are solved from cmake 3.14.1. Once this version is enforced,
# the following can be used:
# target_link_libraries(leveldb SHLWAPI::shlwapi)
