 The _CMakeLists.txt_ and _tricore\_toolchain.cmake_ do the trick. Noteworthy directives are:
  - `set(CMAKE_C_COMPILER tricore-elf-gcc)` chooses the right cross-compiler. Omitting this leads to the use of the system's compiler (host == build == target), which is not - almost for sure - a compier that supports TriCore architecture as a target.
  - `set(CMAKE_SYSROOT /tricore-build-tools/tricore-elf)` sets the compiler _sysroot_, namely the path where libraries (both heaers, under _/include_ and static/dynamic libraries, under _/lib_) like `libc`, `libm`, `crt` (C RunTime), etc. are searched.
