[vtkusers] Error Generating vtkGLSLShaderLibrary.h

[Carl Trapani]

Hi Utkarsh,

THANKS! Adding MinGW and MSYS bin dirs to my system path solved my 
problem (duh ... of course, the Eclipse launched ProcessShader couldn't 
find the MinGW dll ... so add it to the path!).

For others attempting to use Eclipse CDT4 + MinGW 5.1.4 on Win32 (Vista) 
to compile VTK 5.2.1, here is what worked for me:

OS: Vista SP1 (32 bit)
Compiler/Toolchain:
--MinGW 5.1.4 (make sure to install g++ as well as base components. 
DON'T install MinGW make.exe, use MSYS make instead.)
--MSYS 1.0.10 (for make.exe)
----Put the bin directories for both of these tools on your system path 
(Computer ->Properties->Advanced->Environment Variables->System Vars)
IDE: Eclipse Europa C++ (Eclipse 3.3 + CDT 4)
Build Generator: CMake 2.6.1
--out-of-source build
--Select the "Eclipse CDT 4 - Unix Makefiles" generator
--accept all defaults, although I had to set/change VTK_DATA_ROOT and 
CMAKE_INSTALL_PREFIX

I'm testing CDT5 out now. I'll let you know how it turns out.

Cheers,
Carl
