Fix the following build failure without a C++ compiler:
CMake Error at CMakeLists.txt:24 (project):
No CMAKE_CXX_COMPILER could be found.
Tell CMake where to find the compiler by setting either the environment
variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
to the compiler, or to the compiler name if it is in the PATH.

The main CMakeLists.txt file in the project's root directory takes
care of the main project settings like project name and version,
handling the options, finding dependencies, etc.
The src/CMakeLists.txt handles options that are necessary to build
libavrdude library and avrdude binary.
