LLVM_CONFIG on visual studio installation

[IlanHindy]

Hi, My perpouse is to activate cling with Jupyter. On windows with Miniconda. I downloaded the source to visual studio and tried to compile it.

I got the following error 👍

Error CMake Error at C:\Users\IlanH\Source\Repos\cling\CMakeLists.txt:42 (message): llvm-config not found -- LLVM_CONFIG-NOTFOUND Cling C:\Users\IlanH\Source\Repos\cling\CMakeLists.txt 42

I have LLVM on my computer but I could not find in the installation a file named llvm-config. I have in my Miniconda files named LLVM_config.cmake (probably created there because of false installation of xeus-cling) can I use it? Is there a place where there are detaied instructions on how to compile cling on Visual-studio? Ilan

How exactly did you try to compile it?
