Options:
--version LLVM version.
--prefix Installation prefix.
--bindir Directory containing LLVM executables.
--includedir Directory containing LLVM headers.
--libdir Directory containing LLVM libraries.
--cxxflags C++ compiler flags for files that include LLVM headers.
--ldflags Linker flags.
--libs Libraries needed to link against LLVM components.
--libnames Bare library names for in-tree builds.
--components List of all possible components.
--targets-built List of all targets currently built.
Typical components:
all All LLVM libraries (default).
backend Either a native backend or the C backend.
engine Either a native JIT or a bytecode interpreter.
