官方qmake 文档

传入宏

//--无值
DEFINES += PARAM
//--有值
DEFINES += PARAM=\"\\\"我的pro参数\\\"\"

宏参数传入空格或者其他特殊字符

#   "2018-10-05 10:35:00"
DEFINES += _END_TIME_ASCII=\"\\\"\u0032\u0030\u0031\u0038\u002d\u0031\u0030\u002d\u0030\u0035\u0020\u0031\u0030\u003a\u0033\u0035\u003a\u0030\u0030\\\"\"
DEFINES += LIST=\"\\\"12,34,56\\\"\"

复制文件

把头文件复制到目标目录

#copy files
win32{#copy HEADERS to DESTDIR
    src_dir = $$HEADERS
    dst_dir = $$DESTDIR

    #和上面的语句之间需要留一个空行，否则会出错
    src_dir ~= s,/,\,g
    dst_dir ~= s,/,\,g
    system(xcopy $$src_dir $$dst_dir /y /s)
}else{
    system(cp -rv $$HEADERS   $$DESTDIR )
}

自动构建目标平台代码

#--auto build pc/arm
message(--------auto build pc/arm----------------)
if(contains(QMAKE_CC,arm-linux-gnueabi-gcc)){
    message(build arm)
}else{
    message(build pc)
}
