qmake脚本常用变量-创新互联

qmake的常用变量主要解说查看帮助手册Qt 5.12->qmake Manual->Variables
参考：qmake 与 配置文件_丘上人的博客-博客 

E:\workspace\QtWork\qmake\library\qmakeevaluator.cpp：QMakeEvaluator::loadSpec()
单独解析.qmake.super，.qmake.conf，.qmake.cache，获取其中的XQMAKESPEC、QMAKESPEC、QMAKEPATH、QMAKEFEATURES这四个变量的值如果存在的话。解析后上下文立即消失，且对后续没有其他影响。
QMAKESPEC ，qmake采用的架构，根据配置qtcreator时所设置的编译器版本进行识别的
XQMAKESPEC ，目标架构
QMAKEPATH ，qmake 的绝对路径
QMAKEFEATURES ，qmake fetures的绝对路径，QtInstallDir\Qt5.12.0\5.12.0\msvc2015_64\mkspecs\features
_QMAKE_SUPER_CACHE_ ， .qmake.super的绝对路径
_QMAKE_CONF_ ， .qmake.conf的绝对路径
_QMAKE_CACHE_ ，.qmake.cache的绝对路径
_QMAKE_STASH_ ， .qmake.stash的绝对路径

E:\workspace\QtWork\qmake\library\qmakeevaluator.cpp：QMakeEvaluator::loadDefaults()
下面是qmake内置的变量，存放在evaluator的m_option中，
DIR_SEPARATOR  default value in windows \\  default value in linux /
DIRLIST_SEPARATOR default value in windows ;  default value in linux :
_DATE_ 初始化值QDateTime::currentDateTime().toString()
QMAKE_QMAKE  初始化值qmake.exe绝对路径
QMAKE_ARGS  初始化值qmake 传入参数（工程构建步骤中qmake之后的参数）
QMAKE_QTCONF 通过-qtconf参数指定的文件
下面是解析之前通过C++代码初始化的变量
QMAKE_HOST.cpu_count，qmake运行主机的cpu数量
QMAKE_HOST.os  ，qmake运行主机的操作系统名字，可选值有windows，linux
QMAKE_HOST.name ，qmake运行主机名字
QMAKE_HOST.version ，qmake运行主机的操作系统内核版本
QMAKE_HOST.version_string ，qmake运行主机的操作系统产品版本
QMAKE_HOST.arch  ，qmake运行主机的架构，可选值有x86_64，x86，IA64，Unknown
QMAKE_TARGET.arch ,目标架构（5.12.0只对windows有效）x86，x86_64（对于windows下配置vs编译器的qt，qmake会根据path中vs的bin下的架构名字进行解析）


E:\workspace\QtWork\qmake\library\qmakeevaluator.cpp：QMakeEvaluator::evaluateFile()
QMAKE_INTERNAL_INCLUDED_FILES   解析pro文件时背后所用到的配置文件列表，包括conf文件、prf文件、pri文件、prl文件等等脚本文件

E:\workspace\QtWork\qmake\library\qmakeevaluator.cpp：QMakeEvaluator::evaluateFeatureFile()
QMAKE_INTERNAL_INCLUDED_FEATURES  ，解析pro文件时，背后所用到的features文件（.prf文件）


E:\workspace\QtWork\qmake\library\qmakeevaluator.cpp：QMakeEvaluator::visitProFile()
PWD :当前路径

E:\workspace\QtWork\qmake\library\qmakeglobals.cpp：void QMakeGlobals::commitCommandLineArguments()，初始化参数的时候会用到
QMAKE_EXTRA_ARGS
