How QT copies dependent files into the build directory in. Pro files

Add a piece of code to the pro file,

Definereplace (Win32path) {#定义替换

    Win32:1 ~= s|/|\\\\|g# will replace any value that matches the regular expression of the specified value

    Contains (1, ^\\.*):p FX = \ \ #如果value存在于一个被叫做variablename的变量的值的列表中, then succeeds, otherwise fails.

    ELSE:PFX =

    Segs = $ $split (1, \ \) #字符串分割

    out =

    For (SEG, segs) {

        Equals (SEG,..): O UT = $ $member (out, 0) #文档中member函数是只有两个参数的, returns the value of the specified position in the value list of the function

        Else:!equals (SEG,.): O UT + = $ $seg

    }

    Return ($ $join (out, \ \, $ $pfx))

}

win32{

Copydata.commands =$ (copy_file) $ $win 32Path ("$ $PWD/third-part/qxview/lib/qxviewd.dll") $ $win 32Path ("$ $OUT _pwd/ Debug ")

}

$ $PWD represents the path where the. Pro file is located, so $ $PWD represents the current path, followed by a path that relies on the library

$ $OUT _PWD represents the project's build path, which is the output path, which is copied under the Debug folder so that a debug is added later.
