我在我的项目中使用子模块 GitHub，现在我想使用target_include_directoriesfor 将文件包含在我的项目类中

这是我的 cmake 配置

cmake_minimum_required(VERSION 3.9)
project(SpyCBlock)

set(CMAKE_CXX_STANDARD 14)

#bitcoin rpc lib
find_library(bitcoinapi 0.3 REQUIRED)

target_include_directories(rapidjson PUBLIC include/rapidjson/include)

target_include_directories(spycblockrpc PUBLIC include/spycblockrpc)

target_include_directories(btccryptography PUBLIC include/bitcoin-cryptography-library)

add_executable(

        ${PROJECT_NAME}

        #other inclusion file cpp

        #cpp-properties file include
        include/cpp-properties/src/Properties.cpp
        include/cpp-properties/src/PropertiesParser.cpp
        include/cpp-properties/src/PropertiesUtils.cpp

        #include bitcoin-cryptography-library
        include/bitcoin-cryptography-library/cpp/Sha256.cpp
        include/bitcoin-cryptography-library/cpp/Sha256Hash.cpp
        include/bitcoin-cryptography-library/cpp/Utils.cpp

        #include spycblocrpc
        include/spycblockrpc/core/graph/TransactionGraph.cpp
        include/spycblockrpc/core/graph/WrapperInformations.cpp
        include/spycblockrpc/ConfiguratorSingleton.cpp

        include/spycblockrpc/commands/DecodeScriptCommand.cpp
        include/spycblockrpc/commands/DecodeRawTransaction.cpp
        include/spycblockrpc/commands/HeightBlockchainCommand.cpp
        include/spycblockrpc/commands/DecodeBlockAtIndexCommand.cpp

)

#bitcoin rpc lib
target_link_libraries(SpyCBlockTests bitcoinapi)
target_link_libraries(${PROJECT_NAME} bitcoinapi)

运行 CMake 时出现此错误

Starting to parse CMake project.

我画了直接图，所以我画了线的箭头，我是 pixi.js 和 javascript 的新手，我想学习它，你能帮助我如何画一个箭头吗？

这是一个演示，我想将箭头添加到链接中。

这是此类中用于绘制链接的代码

module.exports = function (link, ctx) {
  ctx.lineStyle(link.width, 0x333333, 1);
  ctx.moveTo(link.from.x, link.from.y);
  ctx.lineTo(link.to.x, link.to.y);
}

这是完整的代码

module.exports.main = function () {
  var graph = require('ngraph.generators').balancedBinTree(5);
  var createPixiGraphics = require('../');

  var setting = {
    rendererOptions: {
      backgroundColor: 0xFFFFFF,
      antialias: true,
    }
  }

  var pixiGraphics = createPixiGraphics(graph, setting);
  pixiGraphics.createLinkUI(require('./lib/createLinkUI'));
  pixiGraphics.renderLink(require('./lib/renderLink'));
  pixiGraphics.createNodeUI(require('./lib/createNodeUI'));
  pixiGraphics.renderNode(require('./lib/renderNode'));
  var layout = pixiGraphics.layout;

  // just make sure first node does not move:
  layout.pinNode(graph.getNode(1), true);

  // begin animation loop:
  pixiGraphics.run();
} …
