Fix running tests that require Z3 headers in standalone build. They were wrongly relying on `Z3_INCLUDE_DIR` being passed through from LLVM, which is not the case for a standalone build. Instead, perform `find_package(Z3)` again to find Z3 development files and set `Z3_INCLUDE_DIR`. While at it, handle the possibility that Z3 development package is no longer installed -- run the tests only if both LLVM has been built against Z3, and the headers are still available. https://github.com/llvm/llvm-project/pull/145731#issuecomment-3009487525 Signed-off-by: Michał Górny <mgorny@gentoo.org>
The LLVM Compiler Infrastructure
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called "LLVM". This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
