**LLVM_TARGETS_TO_BUILD**:STRING
Semicolon-separated list of targets to build, or *all* for building all
targets. Case-sensitive. Defaults to *all*. Example:
``-DLLVM_TARGETS_TO_BUILD="X86;PowerPC"``.
``-DLLVM_TARGETS_TO_BUILD="X86;PowerPC;host"``.
The full list, as of March 2023, is:
``AArch64;AMDGPU;ARM;AVR;BPF;Hexagon;Lanai;LoongArch;Mips;MSP430;NVPTX;PowerPC;RISCV;Sparc;SystemZ;VE;WebAssembly;X86;XCore``

**Additional Options**:
- **host**: Automatically detect and build the target corresponding to the host machine's architecture.

For example, on an x86_64 machine, `host` will map to `X86`.
- **Native**: Alias for `host`, used interchangeably to specify the host architecture.

**LLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN**:BOOL
If enabled, the compiler version check will only warn when using a toolchain
