Meson: Issue with CMake-based dependency finder in Meson MSI

[lb90]

Whe using Meson from MSI installer Meson misses some files needed for CMake-based dependencies discovery.

Note: does not happen when running Meson from git checkout

[Joshua-Ashton]

Happens here too on 0.52-1

[Prince781]

Happens on 0.53.2

@jpakkane, I think you're the one who knows the most about the msi packages?

[jpakkane]

This is probably because the data files are not packed in the msi file or they can't be looked up because of path changes. Probably the best change would be to move those files inside the .py files that use them.

[dcbaker]

Are there instructions on how the msi is generated?

[jpakkane]

python msi\createmsi.py in a VS command terminal. You need to install the msm modules with the VS installler by hand, though, because they are no longer installed by defauilt.

[dcbaker]

okay. I have a fix for the missing cmake files in #6829, because they're not in the same place on windows and *nix, hopefully the fix I've come up with would fix the msi installer if we actually had data files.

[dankegel]

This affects me, too.

Falling back to pip install now, I guess.

[dcbaker]

I think this is fixed by https://github.com/mesonbuild/meson/pull/7160.

We haven't made a release since that was merged, but if it isn't fixed in 0.55.0 please reopen this.
