How to install Qt on Windows after building?

Question

I can\'t find any information on how to install Qt built on Windows.
In wiki article How to set up shadow builds on Mac and Linux there\'s description of -prefix

It's very odd people claim that there is no "make install" on Windows.

I have used it many times, and I agree that it's not what it is on other platforms, but it serves its purpose.

How I use Qt's make install on Windows (from cmd):

configure
(n/mingw32-)make
(n/mingw32-)make docs
(n/mingw32-)make install

The make install bit copies all necessary headers to be able to delete your source directory. Delete all objects and unecessary stuff:

del /S /Q *.obj lib\*.dll
rmdir /S /Q docs-build qmake tools src

This allows you to remove the source directory. I don't know what impact this has on debugging Qt source code, but it sure reduces the size of a shadow build. I use it to maintain 32 and 64 bit builds with minimal size.
