Usage: configure [options] [assignments]
用法 :
Configure understands variable assignments like VAR=value on the command line.
Each uppercased library name (obtainable with -list-libraries) supports the
suffixes _INCDIR, _LIBDIR, _PREFIX (INCDIR=PREFIX/include, LIBDIR=PREFIX/lib),
_LIBS, and - on Windows and Darwin - _LIBS_DEBUG and _LIBS_RELEASE. E.g.,
ICU_PREFIX=/opt/icu42 ICU_LIBS="-licui18n -licuuc -licudata".
It is also possible to manipulate any QMAKE_* variable, to amend the values
from the mkspec for the build of Qt itself, e.g., QMAKE_CXXFLAGS+=-g3.
在命令行配置变量,如var=值。这将覆盖从pkg-config获得的变量值
也可以在mkspec中通过操作qmake_*变量来构建Qt应用程序，例如，qmake_cxxflags += - G3。
Note that the *_LIBS* and QMAKE_* assignments manipulate lists, so items
containing meta characters (spaces in particular) need to be quoted according
to qmake rules. On top of that, the assignments as a whole need to be quoted
according to shell rules. It is recommended to use single quotes for the inner
quoting and double quotes for the outer quoting.
顶级安装目录：
Top-level installation directories:
-prefix <dir> ...... The deployment directory, as seen on the target device.
[/usr/local/Qt-$QT_VERSION, $PWD if -developer-build]
部署目录，在目标设备上看到的。
-extprefix <dir> ... The installation directory, as seen on the host machine.
[SYSROOT/PREFIX]
安装目录，在主机上看到的
-hostprefix [dir] .. The installation directory for build tools running on
the host machine. If [dir] is not given, the current
build directory will be used. [EXTPREFIX]
安装目录:在主机上正在编译的生成工具的安装目录。如果未给出，则为当前目录
-external-hostbindir <path> ... Path to Qt tools built for this machine.
Use this when -platform does not match the current
system, i.e., to make a Canadian Cross Build.
为该机器构建的Qt工具路径,当-platform与当前系统不匹配时使用此选项,如交叉编译???
Fine tuning of installation directory layout. Note that all directories
except -sysconfdir should be located under -prefix/-hostprefix:
安装目录布局的微调。请注意，所有目录除sysconfdir应位于在-prefix/-hostprefix指定的目录下面：
-bindir <dir> ......... Executables [PREFIX/bin]可执行文件路径
-headerdir <dir> ...... Header files [PREFIX/include]头文件路径
-libdir <dir> ......... Libraries [PREFIX/lib]库文件路径
-archdatadir <dir> .... Arch-dependent data [PREFIX]依赖平台数据
-plugindir <dir> ...... Plugins [ARCHDATADIR/plugins]插件路径
-libexecdir <dir> ..... Helper programs [ARCHDATADIR/bin on Windows,
ARCHDATADIR/libexec otherwise]
辅助程序(外部调用程序)
-importdir <dir> ...... QML1 imports [ARCHDATADIR/imports]QML1入口
-qmldir <dir> ......... QML2 imports [ARCHDATADIR/qml]QML2入口
-datadir <dir> ........ Arch-independent data [PREFIX]独立的平台数据

-examplesdir <dir> .... Examples [PREFIX/examples]例子目录
-testsdir <dir> ....... Tests [PREFIX/tests]测试目录
-hostbindir <dir> ..... Host executables [HOSTPREFIX/bin]主机可执行程序目录

-hostdatadir <dir> .... Data used by qmake [HOSTPREFIX]qmake使用的数据目录
Conventions for the remaining options: When an option's description is
followed by a list of values in brackets, the interpretation is as follows:
'yes' represents the bare option; all other values are possible prefixes to
the option, e.g., -no-gui. Alternatively, the value can be assigned, e.g.,
--gui=yes. Values are listed in the order they are tried if not specified;
'auto' is a shorthand for 'yes/no'. Solitary 'yes' and 'no' represent binary
options without auto-detection.
选项的约定:括号中的值，解释如下：
(以"-libpng... Select used libpng [system/qt/no]"为例)
1)"yes"不用明确指出(-libpng),括号中其他的值可以作为前缀,如"-qt-libpng";
2)也可以用--libpng=qt的格式来表示
3)"auto"是"yes"和"no"的简写,代表[yes/no]
4)只出现"yes"或"no",说明该选项不能自动检查,裁剪时要特别留意
