Built Native failed

[johnson3d]

1: Built LLVM.sln with vs2022
2: cmake -DCMAKE_INSTALL_PREFIX=../install -DPATH_TO_LLVM=../../../../llvm-project/artifacts/install -G "Visual Studio 17 2022" -A x64 -Thost=x64 ../../..

I will get the output:
Selecting Windows SDK version 10.0.19041.0 to target Windows 10.0.19045.
CMake Error at sources/libClangSharp/CMakeLists.txt:36 (find_package):
Could not find a package configuration file provided by "Clang" with any of
the following names:

ClangConfig.cmake
clang-config.cmake

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

-- Configuring incomplete, errors occurred!

When i set CMAKE_PREFIX_PATH = llvm-project/artifacts/install, That output is same

[johnson3d]

CMAKE_PREFIX_PATH is not important
set
-DClang_DIR=artifacts\install\lib\cmake\clang
everythis is well

Sorry I didn't get to answering this directly, I was busy helping out at Microsoft Build conference the past week.

ClangDir should have been auto resolved relative to PATH_TO_LLVM, but it sounds like there was some machine specific issue that caused that to fail and you found a workaround by resolving the path manually.

For anyone who might find my comment in the future: I encountered this issue and solved it by using an absolute path for PATH_TO_LLVM instead of the relative path shown in the directions.
