[CMake] Set environment variable

[David Cole]

Setting an env var in this manner sets it in the currently running 
environment (a session of cmake).

When it's over, the env var is gone, too. It's set during the adding of 
the test (cmake processing), not during the execution of the test.

You can use the CTEST_ENVIRONMENT variable in a ctest -S script if your 
tests run in a dashboard setting.

Not sure if there's another way to guarantee environment settings at 
test execution time... You could pass the value to the test on its 
command line - then the test itself could do a setenv.


Hope this helps,
David
