I'm working on building LDC in tag v1.18.0. I cloned LDC with `--recursive` option, checked out tag v1.18.0, and execute cmake like below: ``` mkdir build cd build cmake .. ``` But I got the error in cmake execution: ``` CMake Error at /usr/lib/cmake/llvm/LLVMExports.cmake:37 (message): Some (but not all) targets in this export set were already defined. Targets Defined: FileCheck;not Targets not yet defined: .... ``` After investigating, I found the cause is that cmake target "FileCheck`" and "not" are already defined in "ldc/utils/CMakeLists.txt`". I thought that "ldc/utils/CMakeLists.txt`" is written to be loaded after including LLVMConfig because there are some checks for existence of those targets, which is defined in LLVMConfig. But actually "ldc/utils/CMakeLists.txt`" is loaded before LLVMConfig. I cannot understand why this can be built. What should I do for building LDC successfully? My operating system is Arch Linux and LLVM version is 9.0.0.
