Recipe used to publish a trimmed source+build tree directly, with
build-time absolute paths baked into LLVMConfig.cmake (the
LLVMExports.cmake `include()` referenced
/home/runner/work/ci-workflows/ci-workflows/_recipe_work/llvm-
project/{native_build,build}/...). Anything but the worker that
ran the publish step saw `cmake Error: include could not find
requested file` -- CppInterOp's consumer extract to $WS/install/
failed at the host cppinterop-tblgen bootstrap.
Both build stages now run `cmake --install` via
LLVM_DISTRIBUTION_COMPONENTS. The host bootstrap installs
tblgens + cmake-exports + llvm-headers + every transitively-built
LLVM*/clang* lib at OUT_DIR/install/native_build/; the wasm
cross-build installs clang-headers + clang-cmake-exports +
clang-resource-headers + clangInterpreter + cmake-exports +
llvm-headers + every wasm-built LLVM*/clang* lib at
OUT_DIR/install/build/. cmake --install rewrites
LLVMTargets-release.cmake to use `${_IMPORT_PREFIX}`/
`${CMAKE_CURRENT_LIST_DIR}` relative paths, so consumers see
working find_package(LLVM/Clang) regardless of extract path.
LLVM_BUILD_TOOLS=OFF / CLANG_BUILD_TOOLS=OFF on the wasm
configure skip the host binaries; the wasm DIST set drops them
(`llvm-tblgen`, `clang-tblgen`, `llvm-config`, `clang`) to avoid
`ninja install-X` failing at file-not-found. The native DIST is
similarly tightened -- the host bootstrap doesn't need `clang` or
`clangInterpreter`, so neither component is asked for. The
source-tree trim is gone: the install trees are self-contained,
so we no longer ship llvm/{include,cmake} + clang/{include,cmake}
from the build source. Consumer cmake contract in recipe.yaml is
unchanged.
