This indicates that you use the C compiler to link a C++ program.

In your CMakeLists.txt you explicitly set CMAKE_CXX_COMPILER to gcc,
not to g++. In fact, I would not set the compiler variables explicitly
as they are auto-detected.

It may also be a good idea to tell CMake that you are working on a C++
project:

    project(TV6 C++)
