Summary0007097: FindBoost on Linux misinterprets compiler version info for library search if compiler name contains version number
DescriptionIf the compiler name on Linux is e.g. gcc-4.2, then the FindBoost module
searches for boost libraries containing the version string
  -gccg++-4.2 (GCC) 4.2.2
instead of
  -gcc42

The statement
        STRING(REGEX REPLACE ".* ([0-9])\\.([0-9])\\.[0-9] .*" "\\1\\2"
               _boost_COMPILER_VERSION ${_boost_COMPILER_VERSION})

inside FindBoost.cmake seems to fail in this case. The cause is probably the trailing blank required by the regular expression, which is not always there.

The result of this bug is that Boost is never found in this configuration.
Steps To Reproduce
Additional InformationThe output of gcc --version on this machine is
  gcc (GCC) 4.1.1 20070105 (Red Hat 4.1.1-52)
The output of gcc-4.2 --version on this machine is
  gcc-4.2 (GCC) 4.2.2

It would probably be better to use a regular expression such as
  ".*\\(GCC\\) ([0-9])\\.([0-9])\\.[0-9].*"
(untested)
