[OpenIndiana-discuss] CMake can't find LLVM

[w6b7rk5yu4mt25v3 at tutanota.com]

That guy has been haunted me since the first time I posted on illumos topic box. It's not for no reasons I said he is toxic.

Btw, the project I'm trying to build is a programming language that use LLVM as the backend. What CMake failed to find is the LLVM Libraries, not the LLVM Toolchain. CMake has no problems finding and use Clang, and the fact is I use GCC to build that project.

Don't blame CMake too soon. Let's acknowledge that you are a crazy platform that doesn't follow any conventions in FHS. Even FreeBSD with it weirdness FHS by abusing /usr/local since /usr/local is for locally built stuffs, not binary packages, it's somehow still follow a standard FHS that make CMake has no difficulty finding the needed libraries. You are not! You placed everything all over the places, mixing 32 bit and 64 bit libraries, and you expect CMake to be able to correctly find the libraries? Do you pay CMake developers to work on supporting your platform? Are you contributed patches to CMake to make it correctly pick up the libraries from the mess which is your FHS? No. You didn't do anything. You blamed CMake instead. It's like the CMake developer has the responsibility to support all obscure OS in the world! Even me, the human, don't know where you put the LLVM libraries, let alone CMake!

Let's recall that from internet search I know that you used to target 32 bit by default even though your OS is exclusively 64 bit and people has to force it to produce 64 bit binary by -m64!

>From mailing list, it seems you removed 32 bit libraries (that makes the wine users unhappy). If it's the case, why don't you make /usr/lib the default location for 64 bit libraries? WTF is /usr/lib/64? I'm pretty doubt that you are fully 64 bit yet. Btw, if Peter Tribble's answer is right, then the LLVM libraries are not in /usr/lib/64 either. I have personally confirmed that /usr/lib/64/cmake doesn't contain LLVMConfig.cmake or llvm-config.cmake.

I don't want to deal with your crazy platform anymore. I'm currently happy with FreeBSD, where I still need to specify -DCMAKE_PREFIX_PATH, but the FHS is predictable.
