# Cap'n Proto CMake Package Configuration
|
|
#
|
|
# When configured and installed, this file enables client projects to find Cap'n Proto using
|
|
# CMake's find_package() command. It adds imported targets in the CapnProto:: namespace, such as
|
|
# CapnProto::kj, CapnProto::capnp, etc. (one target for each file in pkgconfig/*.pc.in), defines
|
|
# the capnp_generate_cpp() function, and exposes some variables for compatibility with the original
|
|
# FindCapnProto.cmake module.
|
|
#
|
|
# Example usage:
|
|
# find_package(CapnProto)
|
|
# capnp_generate_cpp(CAPNP_SRCS CAPNP_HDRS schema.capnp)
|
|
# add_executable(foo main.cpp ${CAPNP_SRCS})
|
|
# target_link_libraries(foo PRIVATE CapnProto::capnp)
|
|
# target_include_directories(foo PRIVATE ${CMAKE_CURRENT_BINARY_DIR})
|
|
#
|
|
# If you are using RPC features, use 'CapnProto::capnp-rpc' in the target_link_libraries() call.
|
|
#
|
|
# Paths to `capnp` and `capnpc-c++` are exposed in the following variables:
|
|
# 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).
|
|
#
|
|
# For FindCapnProto.cmake compatibility, the following variables are also provided. Please prefer
|
|
# using the imported targets in new CMake code.
|
|
# CAPNP_INCLUDE_DIRS
|
|
# Include directories for the library's headers.
|
|
# 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 (prefer using CapnProto_FOUND in new code).
