[CMake] Setting an environment variable when executing make script

[Carlson Daniel]

Hello and sorry for my late response!

I can not get this to work. When i execute the command COMMAND
${CMAKE_COMMAND} -E ${template.cmake}
  I get an error saying something like:

CMake Error: cmake version 2.6-patch 2
Usage: /home/daniel/Public/cmake-2.6.2/bin/cmake -E [command] [arguments
...]
Available commands:
  chdir dir cmd [args]...   - run command in a given directory

Which means that I can not call cmake -E with a cmake-sript. Do I do
anything wrong? Should it be possible to feed cmake -E with a cmake-script?

Regards Daniel Carlson
