+Subject: [PATCH] Add support for Windows
+
+Ported termkey for windows.
+
+- The TERMKEY_FLAG_NOTERMIOS is ignore in Windows, since there is no termios.
+- The termkey_waitkey() function is not implemented in windows, since there
+  is no poll() alternative.
+- The CMake recipe only supports unibilium, not curses.
