-# Finds the Cap'n Proto libraries, and compiles schema files.
-#
-# Configuration variables (optional):
-# CAPNPC_OUTPUT_DIR
-# Directory to place compiled schema sources (default: the same directory as the schema file).
-# CAPNPC_IMPORT_DIRS
-# List of additional include directories for the schema compiler.
-# (CMAKE_CURRENT_SOURCE_DIR and CAPNP_INCLUDE_DIRS are always included.)
-# CAPNPC_SRC_PREFIX
-# Schema file source prefix (default: CMAKE_CURRENT_SOURCE_DIR).
-# CAPNPC_FLAGS
-# Additional flags to pass to the schema compiler.
-#
-# Variables that are discovered:
-# CAPNP_EXECUTABLE
-# Path to the `capnp` tool (can be set to override).
-# CAPNPC_CXX_EXECUTABLE
-# Path to the `capnpc-c++` tool (can be set to override).
-# CAPNP_INCLUDE_DIRS
-# Include directories for the library's headers (can be set to override).
-# CANP_LIBRARIES
-# The Cap'n Proto library paths.
-# CAPNP_LIBRARIES_LITE
-# Paths to only the 'lite' libraries.
-# CAPNP_DEFINITIONS
-# Compiler definitions required for building with the library.
-# CAPNP_FOUND
-# Set if the libraries have been located.
-#
-# Example usage:
-#
-# find_package(CapnProto REQUIRED)
-# include_directories(${CAPNP_INCLUDE_DIRS})
-# add_definitions(${CAPNP_DEFINITIONS})
-#
-# capnp_generate_cpp(CAPNP_SRCS CAPNP_HDRS schema.capnp)
-# add_executable(a a.cc ${CAPNP_SRCS} ${CAPNP_HDRS})
-# target_link_library(a ${CAPNP_LIBRARIES})
-#
-# For out-of-source builds:
-#
-# set(CAPNPC_OUTPUT_DIR ${CMAKE_CURRENT_BINARY_DIR})
-# include_directories(${CAPNPC_OUTPUT_DIR})
-# capnp_generate_cpp(...)
