           Summary: Driver assumes libc++ headers in /usr/include, libc++
                    installs them into current install location
           Product: clang
           Version: trunk

possible patch for ToolChains.cpp

There is currently a mismatch between where the driver expects to find the C++
headers if  the -stdlib=libc++ flag is used( /usr/include/c++/v1) and where a
libc++ 'install' actually installs them (
${CMAKE_INSTALL_PREFIX}/include/c++/v1 ).

 If the driver and the libraries are explicitly installed into different places
then the user can be expected to have to supply correct -I and -L flags (or
there should be a option to point to a common install area).

 For a simple install to a single area though, Things Should Just Work.

I have attached a patch for ToolChains.cpp that looks in the installation
directory, rather than the fixed location, though a more sophisticated system
could no doubt be devised.
