[vtkusers] Tcl compile error

[Martin Magnusson]

Hello again. I'm still having trouble installing (using Cygwin and gcc 
3.2.2).

I'm compiling a Release build without Tcl and Python, using gcc and g++ 
as C/C++ compilers, respectively.

First, when compiling VTK itself, I get lots of warnings like below, but 
that is maybe not anything to worry about:

- - - -8<- - - - - - - - -
Building object file vtkDataArray.o...
cc1plus: warning: changing search order for system directory 
"/usr/include/w32api"
cc1plus: warning:   as it has already been specified as a non-system 
directory
cc1plus: warning: changing search order for system directory 
"/usr/i686-pc-cygwin/lib/../../include/w32api"
cc1plus: warning:   as it is the same as non-system directory 
"/usr/include/w32api"
- - - -8<- - - - - - - - -

However, when trying to compile the example files cmake reports an error 
referring to Tcl and exits. This is the same both with VTK 4.2 and 4.4. 
Any ideas as to what to try?

Warning: CMake is forcing CMAKE_BUILD_TYPE to "Release" to match that 
imported from VTK.  This is required because projects must use the same 
compiler settings.
   If this message appears for more than one imported project, you have 
conflicting compiler settings and will have to re-build one of those 
projects.
