Minor fix to CMakeLists.txt to disable C++ compiler check

Radek,

You'll find in the following e-mail a patch that disables the unneeded (and sometimes problematic) C++ compiler check from CMakeLists.txt. It has been found while using unionfs-fuse in the context of the Buildroot embedded Linux build system (http://www.buildroot.org), for which we sometimes use toolchains that don't have C++ support.

Thanks,

Thomas

By default, CMake assumes that a project uses both the C and C++ languages, and unionfs-fuse's CMakeLists.txt doesn't explicit which languages it uses. Therefore CMake checks for both a C compiler and a C++ compiler, which prevents from building unionfs-fuse on platforms that don't have a C++ compiler.

We adjust unionfs-fuse CMakeLists.txt to explicity state that we only use the C language, so that the C++ compiler check is no longer performed by Cmake.
