We now have cerec for C, cerec++ for C++ and ceref for Fortran (optional). Source language detection caused issues at link time in the past, especially when linking C++ : for instance, the C++ standard lib would not always be found because clang would be called called instead of clang++. Now, choosing the right compiler is the task of the target application's build system, instead of CERE's automatic language detection.
This could cause issues, for instance when CMake was trying to write .ll files to write protected directories when building test programs

This should avoid issues where cerec was trying to choose the correct LLVM frontent for
compiling, linking... Now this would be the job of build systemcs such as CMake, autotools
This avoids useless compilation steps, and prevents potential issues, for instance when build
systems compile test programs in protected directories.
