[CMake] typo in http://www.cmake.org/cmake/help/cmake-2-8-docs.html#prop_test:FAIL_REGULAR_EXPRESSION

[Tyler Roscoe]

#  FAIL_REGULAR_EXPRESSION: If the output matches this regular
#  expression the test will fail.

If set, if the output matches one of specified regular expressions, the
test will fail.For example: PASS_REGULAR_EXPRESSION
"[^a-z]Error;ERROR;Failed" 



The example should say FAIL_REGULAR_EXPRESSION, not
PASS_REGULAR_EXPRESSION.
