[CMake] Possible set_tests_properties(ENVIRONMENT) bug?

[David Cole]

I think it's just a semicolon problem. Unfortunately for all of us Windows
PATH and CMake both use ";" as their list separator character.

And the set_test_properties ENVIRONMENT property is a semicolon delimited
list of name1=value1;name2=value2;name3=value3;...etc...

To embed ; characters inside of a value, try this after setting NEWPATH and
before calling set_test_properties:
STRING(REPLACE ";" "\\;" NEWPATH "${NEWPATH}")

Let us know if it works for you...

Thanks,
David
