Probably missing dependency during installation

[RuneDominik]

Following the installation instructions in the README, during the "building rune"-step, I ran into a missing prerequisite. The make command in

$ git clone https://github.com/google/rune.git
$ git clone https://github.com/pornin/CTTK.git
$ cp CTTK/inc/cttk.h CTTK
$ cd rune
$ make

resulted in

clang -Wall -g -std=c11 -Wno-varargs -I../../CTTK -DRN_DEBUG -c array.c bigint.c io.c random.c
make[1]: clang: No such file or directory

This was off course easy fixable by installing clang. But since especially clang-14 is specifically stated as prerequisite I wondered if this list is incomplete and clang should be added to the instructions, specifically expanding

$ sudo apt-get install bison flex libgmp-dev clang-14

to

$ sudo apt-get install bison flex libgmp-dev clang clang-14

or if this was a problem on my site. Happy to give further information or to extend the README.

SGTM. I've added clang as you suggest.

@waywardgeek - In the steps for installation; $ cp CTTK/inc/cttk.h CTTK $ cd rune $ make

the make command gives an error as shown below. I completed all commands including the one from @RuneDominik as well. But got stuck in this error

datadraw -h include/dedatabase.h database/Rune.dd make: datadraw: No such file of directory make: *** [Makefile:97: include/dedatabase.h] Error 127

I did some digging in the code and seems like it is in the Makefile; trying to debug further. If you have a solution please let me know.
