CMake errors when building on Alpine Linux

[c0r73x]

Sounds like it could be that ncurses with widecharacter support isn't available in Alpine Linux, maybe we should add a fallback to look for the default version of ncurses if the widecharacter support dosn't exist.

@rendom what do you think?

The ncurses package in alphine seems to be built with --enable-widec or maybe its not used by default?

Ahh, I just noticed Could NOT find Curses (missing: CURSES_INCLUDE_PATH) seems that for some reason Alpine is missing the FindCurses.cmake file. But it's very strange because it should be in the cmake package.

We could fix it by adding the FindCurses.cmake file to ncpamixer, but that just feels wrong. It's better to solve this on Alpine Linux side.

The cmake package has that file

[c0r73x]

Very strange... @FredrikHson do you have any idea why this would happen?

[c0r73x]

Seems we are using our own FindCursesW for some reason. Thats probably why it's not working, we are trying to find out the reason why we created our own file.

[c0r73x]

Hummm, we need to add an option for enabling ncursesw though...

What distro is that? For me it looks fine on Arch

edit: alpine is also fine

[c0r73x]

It's on gentoo, I need to add the flag set(CURSES_NEED_WIDE TRUE) to enable ncursesw. Otherwise it will only use ncurses.

I've added a new flag to the cmake file USE_WIDE, so it looks fine on gentoo now with that flag on.

Humm but now it seems it fails to build on Arch xD something is strang with the CURSES_NEED_WIDE flag on Arch Linux.

[z3ntu]

On Alpine it also fails with CURSES_NEED_WIDE ... I'd rather say Gentoo / CMake is weird :P

EDIT: On Fedora it succeeds with CURSES_NEED_WIDE

[c0r73x]

Hehe, maybe.. I will fix it ;)

[z3ntu]

And Ubuntu is the best because it looks like in your screenshot but fails with CURSES_NEED_WIDE...

[c0r73x]

Fantastic -_- is it Ubuntu specific or is it debian in general?

[c0r73x]

Now it's fixed on Gentoo at least. Not sure if it's worth to spend time to fix Ubuntu (or Debian) since i don't use any of those distros. Better if someone who uses it can do some testing.
