I'm not CMake expert, but with current code and WITH_PYTHON not touched I have following error:
```
CMake Error at third_party/s2geometry/CMakeLists.txt:658 (if):
if given arguments:
"AND" "TRUE"

Odd since this hasn't changed in 5 years.
What's the exact command that fails for you and what cmake version?
There was a problem hiding this comment.
cmake version 3.28.3
I use s2 as submodule with quite complicated setup, so I probably cannot provide exact command.
It uses add_subdirectory(s2geometry)
Python3_FOUNDdefined because other components usefind_package(Python3...)beforeadd_subdirectory(s2geometry)WITH_PYTHONisn't defined soSWIG_FOUNDalso not defined
In general this condition looks quite unusual because
find_package(Some)
if (Some_FOUND)
quite popular cmake construction but not
find_package(Some)
if (${Some_FOUND})
because it will be syntax error if Some_FOUND not defined?
But as I said, I'm not cmake expert so feel free to close if you're thinking it's irrelevant/not necessary/etc
It wasn't issue for me before, because these lines was comment out in my fork

It can became an issue since this efb124d

Maybe you can try following patch in github CI?

The easiest way to test it is to make a PR.

What's the difference between X and ${X} is in cmake?
Maybe the most obvious fix is to add WITH_PYTHON && or wrap in if (WITH_PYTHON).

What's the difference between X and ${X} is in swig?
In cmake you mean?
If I understand right ${X} converts argument to string

I think I find main difference in if (condition) https://cmake.org/cmake/help/latest/command/if.html#variable-expansion but still don't understand why if (${undefined_var} AND ${defined_as_true_var}) doesn't work
