CMake Error: The source directory does not appear to container CMakeLists.txt

[danhab99]

I'm following the instructions to build this tool manually as described in the README.md but the second step isn't working.

This happens just fine

The process done on Linux is roughly:

git clone --single-branch --branch llvmorg-17.0.4 https://github.com/llvm/llvm-project
cd llvm-project
mkdir -p artifacts/bin
cd artifacts/bin
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=../install -DLLVM_ENABLE_PROJECTS=clang ../../llvm
make install

This yeilds an error

Afterwards, you can then build libClangSharp where the process followed is roughly:

git clone https://github.com/dotnet/clangsharp
cd clangsharp
mkdir -p artifacts/bin/native
cd artifacts/bin/native
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=../install -DPATH_TO_LLVM=../../../../llvm-project/artifacts/install
make install

The error happens at the cmake command.

cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=../install -DPATH_TO_LLVM=../../../../llvm-project/artifacts/install 
CMake Warning:
  No source or binary directory provided.  Both will be assumed to be the
  same as the current working directory, but note that this warning will
  become a fatal error in future CMake releases.


CMake Error: The source directory "/home/dan/Documents/install/build-clangsharp/clangsharp/artifacts/bin/native" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.

I'm sure I copy pasted the commands in from the README correctly. Is there something in the documentation I should have noticed?

It's just missing ../../.. as a final argument to specify the directory that contains CMakeLists.txt, which is to say the relative path from the current directory to the repository root.

Boy that fixed it. I submitted a pull request with your suggestion
