These instructions don't work.

$ cmake -DBUILD_SHARED_LIBS=ON ../

  Could not find a package configuration file provided by "LLVM" (requested
  version 6.0) with any of the following names:

    LLVMConfig.cmake
    llvm-config.cmake

  Add the installation prefix of "LLVM" to CMAKE_PREFIX_PATH or set
  "LLVM_DIR" to a directory containing one of the above files.  If "LLVM"
  provides a separate development package or SDK, be sure it has been
  installed.

You must have HERA_WAVM=ON specified somewhere.

https://github.com/ewasm/hera#build-options mentions:

-DLLVM_DIR=… one will need to specify the path to LLVM's CMake file.

If you are sure -DHERA_WAVM=ON wasn't specified, then please upload the CMakeOutput.log and meanwhile add -DHERA_WAVM=OFF.

Please reopen if this issue persists. I believe it was a cmake configuration cache problem on your end.
