+FindNGTCP2
+----------
+
+Find the ngtcp2 library
+
+This module accepts optional COMPONENTS to control the crypto library (these are
+mutually exclusive)::
+
+ OpenSSL: Use libngtcp2_crypto_openssl
+ GnuTLS: Use libngtcp2_crypto_gnutls
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+``NGTCP2_FOUND``
+ System has ngtcp2
+``NGTCP2_INCLUDE_DIRS``
+ The ngtcp2 include directories.
+``NGTCP2_LIBRARIES``
+ The libraries needed to use ngtcp2
+``NGTCP2_VERSION``
+ version of ngtcp2.
