[CMake][Standalone] Rewrite standalone build based on llvm-config. CLANG_PATH_TO_LLVM_*(s) are deprecated.
Checked on VS10(multiconfig) and some singleconfig builders.
* Assumptions
- You should specify llvm-config as LLVM_CONFIG.
CMake could find one in $PATH by default.
- ENABLE_ASSERTIONS obeys LLVM's.
* Use cases
a) With LLVM build tree
Assume llvm-config is in your build tree.
Everything should work as ever.
b) With *installed* LLVM
Assume distributions. The source tree can be optional.
b1) The source tree is provided on the location `llvm-config --src-root`
- Test utils, FileCheck &c., are imported and built in the new tree.
- Gtest is built in the tree if gtest library is not found.
- Lit is used in $(SRCROOT)/utils/lit/lit.py.
b2) The source tree is not provided
- clang and utilities can be built.
- All tests, unittests and check-clang are invalidated and not built.
