Right, PASS_REGULAR_EXPRESSION is being set to "value1" and then to
"value2". You can use set_property(TEST test1 APPEND) to append "value2"
to the existing property value (or use "value1;value2" to set it at
once).

If any one matches, the test is considered to have passed. Maybe you
want "value1.*value2;value2.*value1"?
