make -j8 install DESTDIR=$OUT_ROOT_DIR/$IOS_ARCH解释

这是一个makefile的指令，其中包含以下参数：

- make：表示要使用make工具运行该指令；
- -j8：表示并行处理8个任务，加快编译速度；
- install：表示要将编译后的文件安装到系统中；
- DESTDIR=$OUT_ROOT_DIR/$IOS_ARCH：表示安装路径，$OUT_ROOT_DIR表示输出根目录，$IOS_ARCH表示iOS架构。

这个指令的作用是将编译后的文件安装到指定的iOS架构目录中，并使用8个线程加速处理。

这是一个Qt项目的.pro文件，其中包含了该项目需要使用的库、头文件、源文件等信息的配置。

QT += core 表示该项目需要使用Qt的核心模块。

QT -= gui 表示该项目不需要使用Qt的GUI模块。

CONFIG += c++11 表示该项目需要使用C++11标准。

TARGET = UavRectifyLoadLIb 表示该项目的目标文件名为UavRectifyLoadLIb。

CONFIG += console 表示该项目是控制台应用程序。

CONFIG -= app_bundle 表示该项目不需要生成AppBundle。

TEMPLATE = app 表示该项目是一个应用程序。

SOURCES += main.cpp 表示该项目的源文件为main.cpp。

DEFINES += QT_DEPRECATED_WARNINGS 表示该项目使用了Qt中已经被废弃的API，会产生编译警告。

win32{...} else{...} 表示如果是win32系统，执行前面的语句，否则执行后面的语句。这里是设置DESTDIR的路径。

INCLUDEPATH 和 DEPENDPATH 分别表示头文件和依赖路径。

LIBS 表示需要链接的库文件。

QMAKE_CXXFLAGS_RELEASE 和 QMAKE_LFLAGS_RELEASE 分别表示编译和链接时的参数。

总之，这是一个Qt项目的.pro文件，通过配置各种参数和库文件来构建应用程序。
