Added the clang dependency for Fedora/RHEL systems

[AlexonOliveiraRH]

If the clang package is not present, the following error occurs when running the informed command:

$ mkdir -p build && cd build && cmake .. && make -s
-- The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:3 (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.

Thanks for contributing @AlexonOliveiraRH - I will proceed to merge this into an integration branch where I'll make some follow-up fixes before merging to master. Will update here once in master.

Thanks again @AlexonOliveiraRH - the Fedora dependency update has been merged to master in 3d392ad.

I made some adjustments, please let me know if you think the final documentation is not correct.

Also, the make.sh script has been updated to cover Fedora, so one can do:

./make.sh deps
./make.sh build
./make.sh install

to install dependencies, build and install nchat.

Hey Kristofer. Thank you for accepting my contributions. I see you've made some changes in the code and it seems to be OK now.

Great, thank you so much. I also saw you adjusted the README.md with the correct dependencies now. Thank you for merging this.
