llvm installer on windows missing LLVMConfig.cmake

[funchal]

I have tried both the LLVM 13 and 12 installers (win64 versions) available on github on the Releases page -- both seem to be missing LLVMConfig.cmake, which causes cmake to error with

    CMake Error at CMakeLists.txt:9 (find_package):
      Could not find a package configuration file provided by "LLVM" with any of
      the following names:

        LLVMConfig.cmake
        llvm-config.cmake

I can see this file in the source distribution, so it seems to be just missing in the installer.

LLVMConfigExtensions.cmake is added in this install( statement but not LLVMConfig.cmake.

llvm-project/llvm/cmake/modules/AddLLVM.cmake

Line 1057 in a44ef99

${llvm_cmake_builddir}/LLVMConfigExtensions.cmake

Can confirm that the installer for 13 is missing llvm-config.

Still?

Any news on this as I can't get it working

[retrooper]

Even downgrading to llvm 11 didn't help

[retrooper]

Building LLVM is over 40 gigabytes on my system. Please fix the installer.

[kleinesfilmroellchen]

Building LLVM is over 90 gigabytes on my system and took me five days to get right. Please fix the installer. :^)

Still an issue with 15.0.4

These is just this file LLVMConfigExtensions.cmake , containing a single line:
set(LLVM_STATIC_EXTENSIONS )

I need this in order to build - https://github.com/KhronosGroup/SPIRV-LLVM-Translator

I'd like to resurface this one. I was trying to install https://github.com/p-ranav/fccf on windows, and now it turns out I need to build LLVM from source for that. So this might be a big usability problem for downstream tools that aren't shipping pre-built binaries.

I would vote instead of commenting if I could, sorry for the noise.

Still an issue. Its a shame its not getting any attention and lowers usability
