C++ Meson build: How to select another compiler

I am using Meson for building C++ project and need to set compiler priority to clang instead of default gcc when it avaible. How to do that in meson.build file? Is it possible without additional meson setup args? P.S. if this not possible, how to do the same with Cmake?

Tried to use meson setup --native-file nativefile.ini ./build command to set clang, but if system does not have clang it fails (and also reqiures to manually pass native file to meson). Same with CXX=clang++ meson setup ./build, that is manual, I need autodetect. How to just use meson setup ./build for this to make it system-independent?

Presently Meson is not capable of specifying the default compilers (at least in meson.build). There is an issue for it here. Perhaps one day they will add such a feature.

Edit, while old (2013), I think CMake has the same limitation:

By default, [cmake] searches for a list of known compiler names:
cc, gcc, cl, bcc, xlc, clang
In that order, in PATH.
If you set the CC (or CXX respectively) environment variable, it will use this compiler.
