Correction: the CONFIGURE_ARGS will be overwritten again by
Modules/Compiler/Clang-FindBinUtils.cmake because
MODCLANG_COMPILER_LINKS is set to "No" and the cmake module will force
the compiler version.
Meaning:
Will fail if we switch base to 22 and ports stay 19:

This should work for the migration now:
MODULES += lang/clang
MODCLANG_COMPILER_LINKS = No
MODCLANG_VERSION = 22
CONFIGURE_ARGS+=
-DCMAKE_CXX_COMPILER_CLANG_SCAN_DEPS=${LOCALBASE}/bin/clang-scan-deps-${MODCLANG_VERSION}
# XXX remove after base has llvm/22
BUILD_DEPENDS = devel/llvm/19
Tested with openal and it fallback to 19 for now and if
MODCLANG_COMPILER_LINKS = Yes (tested) or llvm22 is in base (untested)
it should pickup 22.
