Fix test failures caused by regexp-sensitive characters in the build paths Checkout [1] as an example of the test failures. In that particular cases, the failures is caused by the plus sign in the path being pass unescaped (buildd-cmake_2.8.9-1~bpo60+1-armel-3Lvkef) to the regexp. In addition to failures in the log, the following new tests also fail in 2.8.11: 243 - CTestTestMemcheckUnknown (Failed) 244 - CTestTestMemcheckUnknownQuoted (Failed) 248 - CTestTestMemcheckDummyValgrindFailPre (Failed) 249 - CTestTestMemcheckDummyValgrindFailPost (Failed) 250 - CTestTestMemcheckDummyPurify (Failed) 251 - CTestTestMemcheckDummyBC (Failed) 253 - CMake.List (Failed) [1] https://buildd.debian.org/status/fetch.php?pkg=cmake&arch=armel&ver=2.8.9-1~bpo60%2B1&stamp=1369243896 2013-06-03 18:42:12 +04:00			`macro(REGEX_ESCAPE_STRING _OUT _IN)`
