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