Summary0011679: CMAKE_FORCE_C_COMPILER fails to parse compiler name that contains a version number
DescriptionUsing the following commands:
  FIND_PROGRAM (xcc arm-eabi-gcc)
  CMAKE_FORCE_C_COMPILER (${xcc} GNU)
works as expected.

RANLIB and AR commands are mapped to the same target, namely:
arm-eabi-ranlib and arm-eabi-ar
  
However, when a version is specified:
  FIND_PROGRAM (xcc arm-eabi-gcc-4.5.2)
  CMAKE_FORCE_C_COMPILER (${xcc} GNU)
RANLIB and AR commands are left to the default, host tools (which lead to later compilation errors)

In this latter case, the _CMAKE_TOOLCHAIN_PREFIX is left empty. It seems that the compiler string parser is in trouble.
Steps To Reproduce
Additional InformationThe issue occurs whatever the platform (at least tested on Cygwin and Mac OS X), and it seems it may also occur with CMAKE_C_COMPILER.

This is the regexp which is used:
IF (COMPILER_BASENAME MATCHES "^(.+-)g?cc(\\.exe)?$")

so it would match "arm-eabi-gcc.exe" and "arm-eabi-gcc", but it doesn't match arm-eabi-gcc-x.y.z(.exe)?.
I'll have a look.

I changed the regex so it now accepts a version number and pushed this to the next branch.
Not sure whether it will still make it into 2.8.4.
