Hello everyone! I cannot get CMake to find my Python libraries; I’m getting this error.
I’m on MSYS2 on Windows 10 (which I think might be part of the problem).

Indeed, `MSYS2` environment should be used coherently (i.e. all tools must be from the same environment).
First question: what do you want to use: `MSYS2` or `MINGW64`? (i.e. what is the value of environment variable `MSYSTEM`?).
If it is `MSYS2`, you **must** use the `cmake` tool provided by this environment (other `cmake` tools will not work as expected) and also use the python from this environment (typical packages `msys/cmake`, `msys/python` and `msys/python-devel`).
If it is `MINGW64`, you can use `Windows` `cmake` or `MNGW64` `cmake` (package `mingw64/mingw-w64-x86_64-cmake`) but you must have consistency between python and the compiler: use Microsoft compiler with standard python (from `python.org`) or use `GNU` `gcc` with python provided by `MINGW64` environment (package `mingw64/mingw-w64-x86_64-python`).

Hi Marc!
I’m actually using CLANG64 - it looks like CMake can find the wrong Python interpreter if you have multiple ones installed (clang64/python3, msys/python3).
Even though the clang python was first in my path, CMake ignored the following options to continue to find the wrong Python:
PYTHON3\_EXECUTABLE
PYTHON3\_INCLUDE\_DIR
PYTHON3\_LIBRARY
PYTHON\_EXECUTABLE
PYTHON\_INCLUDE\_DIR
PYTHON\_LIBRARY
In the end, I uninstalled msys/python, forcing CMake to find the correct Python, and all was well. It was extremely frustrating.
I wonder if it is some mistake of mine, in the project I was building, or if it was an issue with CMake.

If you want to specify a `Hint` variable, use the correct one!
If you request `Python3` package, `Python3_EXECUTABLE` can be specified. Case is important, `PYTHON3` in uppercase is not correct. And the same of `PYTHON` or `Python` which are irrelevant in this case.
If you request `Python` package, `Python_EXECUTABLE` can be used, nothing else!
And specifying the executable is enough, all other artifacts are deduced from the interpreter itself.
And to finish, without a full snippet showing exactly what are the variables you have defined and how you call the `find_package`, hard to say more…
