ImportLLVM Module

Module imports LLVM into the ComputeAorta build by pulling in LLVM CMake modules from the install directory of a build.

User option CA_LLVM_INSTALL_DIR is required to be set to the filepath of the LLVM install before including this module. The option CA_RUNTIME_COMPILER_ENABLED is also required to be TRUE to use this module, otherwise a LLVM-less offline build is desired.

set(CA_LLVM_INSTALL_DIR "<path/to/install/directory>")
set(CA_RUNTIME_COMPILER_ENABLED TRUE)
include(ImportLLVM)

Using this location we append the directories containing LLVM CMake modules to CMAKE_MODULE_PATH, and import the following LLVM modules:

• LLVMConfig for LLVM.

• ClangTargets for Clang.

Once the modules are included we verify the LLVM version is supported and set some additional compile definitions.

CA_LLVM_VERSIONS

Defines a list of supported LLVM versions, used to verify that LLVM_PACKAGE_VERSION from the imported LLVM install is a supported version.
