[vtkusers] help to change compiler

[Mathieu Malaterre]

Hi Subir,

	Please keep posting to the ML, my Spam filter is very aggressive on 
personal emails ;-)

	Anyway I still don't understand where exactly is your problem ? Since 
you are posting to the VTK ML, I assumed you were trying to compile VTK, 
right ? If not then this is not the proper ML. Are you looking for 
information about CMake ? If so the CMake book can be found at:

    http://www.kitware.com/products/cmakebook.html

	Otherwise there are lots of freely available information on the net. 
And to get specific help on CMake, I'd suggest you to subscribe to the 
CMake ML, you can find it at:

   http://www.cmake.org/HTML/MailingLists.html

As for you specific question to set a specific compiler I repeat that 
the steps are simply:

cd MyProject/
mkdir MyProject-mpicc
cd MyProject-mpicc
export CC=mpicc
export CXX=mpic++
cmake /full/path/to/My/Project


   Calling "cmake ." will do an 'in source' built and you really don't 
want to do that in a multiple compilers environment.

HTH,
Mathieu
