[Buildroot] [PATCH 0 of 1] Minor fix to CMakeLists.txt to disable C++ compiler check

[Thomas Petazzoni]

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

Disable check for C++ compiler

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.
