What were you trying to do?

I was trying to compile Natron using CMake Ninja workflow (cmake -DCMAKE_BUILD_TYPE=Debug ..) from a created build folder in Natron's repo folder, and the shiboken blender libraries evaluates to "Not Found".

Build fails after Ninja command in the folder due to linking errors because of apparent missing Qt dependencies (if I'm understanding correctly).

What did you expect to happen? What happened instead?

I expected the debug build to succeed.

Step-by-step reproduction instructions

1. Git pull Natron recursive (git clone --recursive https://github.com/NatronGitHub/Natron.git). After installing dependencies through msys2 man -S mingw-w64-x86_64-natron-build-deps-qt5, as laid out in comment here
2. install cmake and ninja through pacman, cd to repo and mkdir Build && cd Build
3. use command cmake -DCMAKE_BUILD_TYPE=debug .. after which you should get this output

-- SHIBOKEN_PYTHON_LIBRARIES computed to value: 'PYTHON_DEBUG_LIBRARY-NOTFOUND'
-- libshiboken built for Release
-- Configuring done (0.4s)
-- Generating done (0.2s)

4. ninja command fails with linking errors.

Error output:

C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/14.1.0/../../../../x86_64-w64-mingw32/bin/ld.exe: 
cannot find -lPYTHON_DEBUG_LIBRARY-NOTFOUND: No such file or directory
collect2.exe: error: ld returned 1 exit status
ninja: build stopped: subcommand failed.

Additional details

Release build type works just fine according to the build process.

I tried to debug the cmake issue but it's a bit too complicated as I don't fully understand how Shiboken is being used.
