the NSIS installer because so far it contains hardcoded paths for this location.

Source changes:

Next you need to shift some files around. For convenience we've made an archive
that handles all the changes for you. Download it and unpack to qgis source directory:
Instead of shifting around files, you could use CMake. CMake compiles
raster, compaser, legend, gui and core libraries into one core
library. So it is not 100% compatible with 'normal' 0.8 Makefiles.
Below are the steps to configure and make the source. The building
takes plac in a separate directory from the source. If you have built
the source with 'normal' Makefiels first, please do a make clean (or
remove and check out everything). Previoussly made intermediate files
can disturb the CMake process.

List of what has been changed / added by this archive to enable compilation:
As a background read

- moved qgscsexception.h, qgsspatialrefsys* and qgscoordinatetransform* into core dir from gui
- moved qgspluginregistry.* from core to gui
- qgsspatialrefsys.cpp - commented out SRS validation using projection selector
- qgsspatialrefsys.cpp - commented out lines using qgsproject as it depends on gui stuff
- qgsdistancearea.cpp - commented out lines using qgsproject as it depends on
gui stuff and moved to core
- lexer and parser generated by genlexyacc.bat
- added custom qgsconfig.h and qgssvnversion.h
*) Make sure %QTDIR%\bin;c:\msys\local\bin;c:\msys\bin;c;\msys\mingw\bin is in your Path

*) Start a cmd.exe window ( Start -> Run -> cmd.exe ) if you don't have one already.

*) > mkdir build

Now open the qt command shell (or start "cmd" and run c:\Qt\4.2.0\bin\qtvars.bat)
*) > cd build

cd c:\dev\cpp\qgis
*) > cmakesetup ..

This will compile both debug and release version. To make just a one of them
use "make debug" or "make release" respectively.
If asked, you should chose 'MSYS Makefiles' as generator.

Note: debug version uses debug version of Qt library thus if linking fails
on not founding library QtSvgd4 (or similar), you need to compile them
as described in section for Qt.
All dependencies should be picked up automatically, if you have set
up the Paths correctly. The only thing you need to change is the
installation destination and/or set 'Debug'.

Running: (optional)

After successfull make you can run QGIS directly from the directory
where it has been built: qgis-debug and/or qgis-release in qgis root dir.
You only need to add data files - we have provided an archive for convenience
which you can just unpack there and run QGIS:
*) Now, start sh.exe and run 'make.exe install' from within that shell
It should now start compiling. The reason for this is that we use
the mingw compiler included in the msys tar, but that compiler is
not found from within sh.exe. (MSYS magic). So, if you delete
CMakeCache, you have to generate it from cmd.exe.

Then just run qgis.exe

GDB: (optional)

If you plan to do some debugging, download and install gdb-6.3.2.exe from

and install to c:\msys\mingw
Why not run make from cmd.exe? Because creating 'qgssvnversion.h'
requires the 'mv' command...

*) Make sure to copy all .dll:s needed to the same directory as the
qgis.exe binary is installed to, if not already done so.

Create the installation package: (optional)
