ctest: No tests were found

[ntrel]

I'm new to cmake and I'm following the instructions here: https://github.com/modern-cmake/cppfront#find-package

$ cmake --version
cmake version 3.22.1

$ cmake -S cppfront -B build -DCMAKE_BUILD_TYPE=Release
CMake Error: The source directory "/home/nick/git/cmake-cppfront/cppfront" does not appear to contain CMakeLists.txt.

I removed -S cppfront and updated cmake and it generates build/Makefile. Running that works.

Also, how do I run the tests?

Running ctest I get:

Test project /home/nick/git/cmake-cppfront/regression-tests
No tests were found!!!

You aren't following the directions to the letter. You cloned this repository to a directory called cmake-cppfront and then cd'd into it. The instructions in the README show cloning this repository into a directory called cppfront, not entering it, and using CMake to build it fully out-of-source.

ctest must be run from the build folder, not from the regression tests folder. This is not in the README right now, but should be.

OK, because I already checked out hsutter/cppfront.

I tried running it from every folder I could think of yesterday. I tried the updated commands today, no luck:

$ ctest --test-dir build
Internal ctest changing into directory: /home/nick/git/cmake-cppfront/build
Test project /home/nick/git/cmake-cppfront/build

You don't need to separately check out upstream cppfront. It's included already as a submodule.

At this point, I cannot help you further without you posting a complete, unedited log of every command you ran leading up to this error, starting from a known directory, downloading this repository and building it. I cannot reproduce it locally.

I was using that before I realized I needed this repo to run the tests. Just mentioning it because that workflow is probably common for contributors (it's not ideal that this repo has the same name as a submodule repo).

This is an unedited log of commands I just ran. I didn't checkout the repo again because that was too awkward, but you can see from git status and git show (at the end) what I have (checked out yesterday).
