Qt配置编译依赖

显示指定依赖关系，自动调整编译顺序

TEMPLATE = subdirs
SUBDIRS = core gui plugins tests

gui.depends = core           # gui 依赖 core
plugins.depends = core gui   # plugins 依赖 core 和 gui
tests.depends = core         # tests 仅依赖 core

配置编译顺序

TEMPLATE = subdirs
CONFIG += ordered
SUBDIRS = core gui plugins tests  # 严格按顺序构建：core → gui → plugins → tests
