Change code from windows to linux

How can I modify this code to linux? I need an alternative to #include<windows.h> to make this code:

GetCursorPos(&cursor);
x = cursor.x;
y = cursor.y;

Sleep(2000)
SetCursorPos(x, y);

mouse_event(MOUSEEVENTF_LEFTDOWN, x, y, 0, 0);
mouse_event(MOUSEEVENTF_LEFTUP, x, y, 0, 0);
