[CMake] XCode + GCC 4.2

[Hai Nguyen]

Hi,

I can't seem to get the combination of XCode and GCC 4.2 to be happy with
CMaka. I've tried several different ways to set the compiler version.
Setting the CMAKE_C/CXX_COMPILER doesn't seem to work. But if i set the
environment variabes, CMake comes back and tells me something like this:

  Run Build Command:/usr/local/bin/cmakexbuild -project
  CMAKE_TRY_COMPILE.xcodeproj build -target cmTryCompileExec -configuration
  Debug

  2009-12-18 00:50:45.858 xcodebuild[42636:331b] Warning: Couldn't discover
  the 'gcc-4.2' compiler's built-in search paths and preprocessor
definitions
  for language dialect 'c'.  This may lead to indexing issues.

  Compiler: /Developer/Library/Xcode/Plug-ins/GCC
  4.0.xcplugin/Contents/Resources/gcc-4.2

  Reason: sh: /Developer/Library/Xcode/Plug-ins/GCC
  4.0.xcplugin/Contents/Resources/gcc-4.2: No such file or directory

What am I missing with here...?

Thanks,
Hai
