Why can Meson not find existing /usr/lib/libclang.so?

[metaleap]

So /usr/lib/libclang.so exists and my executable has dependency('clang', include_type: 'system', static: false) in its dependencies, resulting in:

Found pkg-config: YES (/usr/bin/pkg-config) 2.3.0
Found CMake: /usr/bin/cmake (3.31.4)
Run-time dependency clang found: NO (tried pkgconfig and cmake)

../../meson.build:102:12: ERROR: Dependency "clang" not found, tried pkgconfig and cmake

(Same with libclang instead of just clang.)

However the very same mechanics but with SDL2 in place of clang work just fine. Why could that be and what was I missing?

meson-log.txt

The log file says:

Package clang was not found in the pkg-config search path.
Perhaps you should add the directory containing `clang.pc'
to the PKG_CONFIG_PATH environment variable
Package 'clang' not found

This is bothersome because there is no clang.pc file anywhere on this system and that env var is empty. Everything about clang and llvm is already fully installed in terms of packages.

I was kinda assuming that /usr/lib is a standard lib search path, at least for linkers.

Because #13134 hasn't landed. You have two choices with clang:

1. you can use "method: 'cmake'"
2. you can use meson.get_compiler('c').find_library('clang')

Many thanks @dcbaker will do, and subscribed to that PR =)
