Hi Vladimir,

Actually, I don't need to set it globally. It is enough for me to set it just
for a unit test process invoked by bjam. I thought of something like this:

rule set-env-var ( properties * )
{
  local variant = [ feature.get-values <variant> : $(properties) ]
  #something like: set MY_ENV_VAR =/some_dir/$(variant)
}

unit-test my-test
  : test.cpp
  : <conditional>@set-env-var
  ;

Is something like this achievable?

Thanks,
Jarda
