+# - Find libsinsp and libscap
+# Find libsinsp and libscap includes and libraries.
+# Adapted from FindZSTD.cmake.
+#
+# This module will look for libsinsp and libscap using pkg-config. If that
+# fails, it will search ${SINSP_INCLUDEDIR} and ${SINSP_HINTS}/include
+# for the libsinsp and libscap include directory and ${SINSP_LIBDIR} and
+# ${SINSP_HINTS}/lib for the libsinsp and libscap libraries.
+#
+# It will set the following variables:
+#
+#  SINSP_FOUND          - True if libsinsp found.
+#  SINSP_INCLUDE_DIRS   - Where to find sinsp.h, scap.h, etc.
+#  SINSP_LINK_LIBRARIES - List of libraries when using libsinsp.
+
+# You must manually set the following variables:
+#  FALCO_PLUGINS        - Paths to plugins built from https://github.com/falcosecurity/plugins/.
+
+# To do:
+#  SINSP_DLL_DIR        - (Windows) Path to the libsinsp and libscap DLLs
+#  SINSP_DLL            - (Windows) Name of the libsinsp and libscap DLLs
