meson: meson 1.1.0 regression: Dependency "llvm" not found

Describe the bug The update to meson 1.1.0 breaks the detection of LLVM in a mingw cross-compilation context The meson version 1.0.1 is ok on the same testcase

To Reproduce meson.build:

project('simple', ['c', 'cpp'])

llvm_modules = ['bitwriter', 'engine', 'mcdisassembler', 'mcjit', 'core', 'executionengine', 'scalaropts', 'transformutils', 'instcombine']
dep_llvm = dependency('llvm',
   version : '>=13.0',
   modules : llvm_modules,
   required : true,
   static: true,
   include_type : 'system',
)

executable('myexe', 'main.cpp')

returns:

Expected behavior Reverting to meson 1.0.1 I get a correct detection:

it also needs the llvm package:
