[cmake] Add LLVM_TARGET_TRIPLE_ENV to LLVMConfig.cmake.in (#158303) LLVM has a mechanism to switch the default target: LLVM_TARGET_TRIPLE_ENV. For example, regression tests with lit use this CMake variable. It matters only when building LLVM, not the other projects. Therefore, if they are built standalone, the value of the CMake variable should be propagated. In fact, however, it is not. This patch fixes it.
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.
Consult the Getting Started with LLVM page for information on building and running LLVM.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
