# NotepadPluginConfig.cmake
# 用于 Notepad-- 插件实现的 CMake 模块初级定义

# 在 Linux 中，它的布局应该如下：
# /usr/lib/x86_64-linux-gnu/cmake/NotepadPlugin/NotepadPluginConfig.cmake

# 在 插件开发层中，它的使用如下：
    # 1. 查找 NotepadPlugin 模块
        # find_package(NotepadPlugin)
    # 2. 使用 add_notepad_plugin(<模块名称> <源代码、资源文件> [...])
        # add_notepad_plugin(<plugin_name> <plugin_srcs> ...)

# 一些无关紧要的部分，如果需要实现插件安装操作时，即可进行使用
# include(CMakePackageConfigHelpers)
# include(GNUInstallDirs)
 
# 主要内容，在构建时的填充
