我正在尝试使用Windows 10和Qt5.12构建项目。小程序正在使用here可用的smtp协议。我可以确认我的Windows上具有OpenSSL 1.1.1c（2019年5月28日）。在我的Ubuntu 19.04上，相同的程序可以正常编译并运行，但不能在Windows上运行。

我将存储库git clone Windows this post之后{{3}}，并且程序正确构建。

问题是，当我运行它时，它cannot find the executable并在要求它，因为可以从下面的打印屏幕中看到它：

这是我的.pro文件：

QT += quick quickcontrols2 concurrent network core gui

CONFIG += c++11

# The following define makes your compiler emit warnings if you use
# any Qt feature that has been marked deprecated (the exact warnings
# depend on your compiler). Refer to the documentation for the
# deprecated API to know how to port your code away from it.
DEFInes += QT_DEPRECATED_WARNINGS

TARGET = SMTPEmail
DEFInes += SMTP_BUILD

# You can also make your code fail to compile if it uses deprecated APIs.
# In order to do so,uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFInes += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

在我的桌面上，会自动创建build文件夹，并认为可执行文件应该在这里。在下面，我还附上build文件夹中内容的打印屏幕：

最初，此项目已部署在Ubuntu上，这丝毫没有问题。我git clone回购了我的Windows，添加了丢失的SMTP_BUILD，但是我无法对打印屏幕上的窗口正在询问的可执行文件进行优化。最后一步我缺少什么？

非常感谢您指出正确的方向。
