qt 维护x86和arm两套编译环境

1、中间库：

中间库都放在middlewares目录，include头文件相同，所以不需要特殊处理，只要特殊处理lib安装目录，

示例pro文件如下：

TEMPLATE = lib
TARGET = ime
VERSION = 1.0.0
DEPENDPATH += .
INCLUDEPATH += .

CONFIG += staticlib

inc.files =  \
           xinputmethod.h

inc.files +=  $$HEADERS（引用变量的方法）

inc.path = ../includes

DEFINES += X86

contains( DEFINES, X86 ) {
    message( "Configuring for X86 build..." )
    target.path = ../x86libs

} else {
    message( "Configuring for arm build..." )
    target.path = ../libs
}

INSTALLS += inc  target

2、应用程序方面：

pro文件中通过X86宏来控制链接库：

#DEFINES += X86
contains( DEFINES, X86 ) {
    message( "Configuring for X86 build..." )
    LIBS += -L /opt/qt-everywhere/marvell/APP/middlewares/x86libs/ -lime

} else {
    message( "Configuring for arm build..." )
    LIBS += -L /opt/qt-everywhere/marvell/APP/middlewares/libs/ -lime
}

INCLUDEPATH += /opt/qt-everywhere/marvell/APP/middlewares/includes
DEPENDPATH += /opt/qt-everywhere/marvell/APP/middlewares/includes

OTHER_FILES += \

Manually configuring shadow build in qmake

 mkdir my_shadow_build
 cd my_shadow_build
 qmake ../my_src_dir
