 ### Prerequisites

 - QT 5.12 *(lower versions might work but it wasn't tested)*
- uuid _(usually included in some other package, for example it's ***libutil-linux*** in archlinux)_
 - lmdb
 - CMake 3.0 or higher
 - qxmpp 1.1.0 or higher
 - KDE Frameworks: kwallet (optional)

 Squawk requires Qt with SSL enabled. It uses CMake as build system.

+Please check the prerequisites and install them before installation.
+
+#### For Windows (Mingw-w64) build
+
+You need Qt for mingw64 (MinGW 64-bit) platform when installing Qt.
+
+The best way to acquire library `lmdb` and `boost` is through Msys2.
+
+First install Msys2, and then install `mingw-w64-x86_64-lmdb` and `mingw-w64-x86_64-boost` by pacman.
+
+Then you need to provide the cmake cache entry when calling cmake for configuration:
+
+```
+cmake .. -D LMDB_ROOT_DIR:PATH=<Msys2 Mingw64 Root Directory> -D BOOST_ROOT:PATH=<Msys2 Mingw64 Root Directory>
+```
+
+`<Msys2 Mingw64 Root Directory>`: e.g. `C:/msys64/mingw64`.
+
+---

 There are two ways to build, it depends whether you have qxmpp installed in your system
