'File name too long' error example

Whilst trying to build the WebKit GTK version using the command:
./Tools/Scripts/build-webkit --gtk

I am encountering a 'File name too long' error in multiple places (please see attachment for example of error output).  

As far as I know the WebKit GTK buildbot builds do not seem to be having this problem.

Some details of my machine configuration:
Architecture: x86_64
Linux Distribution: Ubuntu 12.04
GCC/G++ version: 4.8
CMake version: 2.8.7

Interesting. The bug fix/behaviour change was introduced between CMake 2.8.7 and 2.8.8 in http://cmake.org/gitweb?p=cmake.git;a=commit;h=8adaee2b0b2651cfd93bb4a915d11bdd4cba1b51.

I don't see a problem with this patch if we plan on supporting CMake 2.8.7 for a long time. I'd guess there are other places where we are passing lists to INCLUDE_DIRECTORIES(), have you checked that?

I just checked - I cant see any other occurrences of lists passed to INCLUDE_DIRECTORIES() in quotes.

Cool, thanks for checking. Looks good from my side.
