jpayne@68 1 # Cap'n Proto CMake Package Configuration
jpayne@68 2 #
jpayne@68 3 # When configured and installed, this file enables client projects to find Cap'n Proto using
jpayne@68 4 # CMake's find_package() command. It adds imported targets in the CapnProto:: namespace, such as
jpayne@68 5 # CapnProto::kj, CapnProto::capnp, etc. (one target for each file in pkgconfig/*.pc.in), defines
jpayne@68 6 # the capnp_generate_cpp() function, and exposes some variables for compatibility with the original
jpayne@68 7 # FindCapnProto.cmake module.
jpayne@68 8 #
jpayne@68 9 # Example usage:
jpayne@68 10 # find_package(CapnProto)
jpayne@68 11 # capnp_generate_cpp(CAPNP_SRCS CAPNP_HDRS schema.capnp)
jpayne@68 12 # add_executable(foo main.cpp ${CAPNP_SRCS})
jpayne@68 13 # target_link_libraries(foo PRIVATE CapnProto::capnp)
jpayne@68 14 # target_include_directories(foo PRIVATE ${CMAKE_CURRENT_BINARY_DIR})
jpayne@68 15 #
jpayne@68 16 # If you are using RPC features, use 'CapnProto::capnp-rpc' in the target_link_libraries() call.
jpayne@68 17 #
jpayne@68 18 # Paths to `capnp` and `capnpc-c++` are exposed in the following variables:
jpayne@68 19 # CAPNP_EXECUTABLE
jpayne@68 20 # Path to the `capnp` tool (can be set to override).
jpayne@68 21 # CAPNPC_CXX_EXECUTABLE
jpayne@68 22 # Path to the `capnpc-c++` tool (can be set to override).
jpayne@68 23 #
jpayne@68 24 # For FindCapnProto.cmake compatibility, the following variables are also provided. Please prefer
jpayne@68 25 # using the imported targets in new CMake code.
jpayne@68 26 # CAPNP_INCLUDE_DIRS
jpayne@68 27 # Include directories for the library's headers.
jpayne@68 28 # CANP_LIBRARIES
jpayne@68 29 # The Cap'n Proto library paths.
jpayne@68 30 # CAPNP_LIBRARIES_LITE
jpayne@68 31 # Paths to only the 'lite' libraries.
jpayne@68 32 # CAPNP_DEFINITIONS
jpayne@68 33 # Compiler definitions required for building with the library.
jpayne@68 34 # CAPNP_FOUND
