# ========  手动构建 libromfs-generator ========
# 本项目支持使用 libromfs 将主程序和资源文件打包在一起，避免额外的文件依赖
# libromfs-generator 的作用是将资源文件转换为 cpp 源码，并在后续的编译过程中链接进主程序
# 在跨平台编译时，有两种解决方案：
# 1. 提前编译host机器格式的 libromfs-generator
# 2. 设置 CMAKE_CROSSCOMPILING_EMULATOR 以在 host 模拟运行 libromfs-generator
# 此脚本即用来生成 host机器格式的 libromfs-generator

# ======== Manually building libromfs generator ========
# This project supports using libromfs to package the main program and resource files together to avoid additional file dependencies
# The function of libromfs-generator is to convert resource files into cpp source code and link them into the main program
# There are two solutions for cross-platform compilation:
# 1. Pre-compile libromfs-generator in the format of the host machine.
# 2. Set CMAKE_CROSSCOMPILING_EMULATOR to simulate execution libromfs-generator on the host.
# This script is used to generate libromfs-generator in the format of the host machine.
