How do I set an environment variable so that it is visible globally in CMake? Specifically, I want to have it visible when I run something like:

#-----------------------------------
# set the environment variable value
set( ENV{myVariable} ... )

# run a test through a CMake script that requires the environment variable set above.
add_test( myTest
  ${CMAKE_COMMAND}
  -D exe_name:STRING=myExecutable
  -P ${PROJECT_SOURCE_DIR}/test_problems/run_test.cmake
  )
#-----------------------------------

In the "run_test.cmake" file I would like to have "myVariable" available as an environment variable, but it is not, despite the fact that it was set prior to the execution of "run_test.cmake".

What am I missing here?
