meson does not support many compiler and this makes all projects using meson unusable

[winspool]

User experience: unusable build system
I tried a project, which depends on "meson",
and my user experience is: "unusable build system"

Describe the bug
All projects using meson are broken,
when the project user tries to use a compiler different from the few compilers supported by meson.

Examples for my tries using the "criterion" project, which depends on "meson":

CC=tcc  CFLAGS="-v"  meson  setup

../meson.build:1:0: ERROR: Unknown compiler(s): [['tcc']]

Next try:

CC=owcc  CFLAGS="-v -blinux -I$WATCOM/lh"  meson  setup

../meson.build:1:0: ERROR: Unknown compiler(s): [['owcc']]

See also: Snaipe/Criterion#514

To Reproduce

• checkout criterion from https://github.com/Snaipe/Criterion
• create a build dir
• cd into the build dir
• first try: CC=tcc CFLAGS="-v" meson setup
• second try: CC=owcc CFLAGS="-v -blinux -I$WATCOM/lh" meson setup

Expected behavior
A build system has to work

system parameters

• native build, x86_64
• ubuntu 2304 (lunar)
• python 3.11.4
• meson 1.0.1
• ninja 1.11.1
