Also compare against existing content lists in a more forgiving way.
The first improvement makes it possible to use relative paths in openmw.cfg without the launcher canonicalising them.
This was really annoying if you used a relative path on purpose.
It also stops the launcher converting all paths to Qt's convention, where forward slashes are used on Windows even though they're not native.
The engine doesn't care, so you could always put either in the config file, but the launcher wouldn't stand for that, and would make them match.
To make this work, we need to store a path's originalRepresentation in the content list, compare paths loaded from openmw.cfg based on their originalRepresentation, and convert paths from originalRepresentation to absolute value when loading them from a content list.
The second improvement means that paths that are equivalent, but expressed differently (e.g. mismatched case on Windows, mismatched separators on Windows, or mild differences like unnecessary `./`es and doubled separators) don't trigger the creation of a new effectively-identical content list.
To make this work, we had to switch the comparison to lexicaly normalise the path first.
It could only be lexical normalisation as originalRepresentation might be absolute, relative, or absolute-but-based-on-a-path-slug, and we didn't want slugs to break things or relative paths to count as equivalent to absolute ones that refer to the same file.
The comparison is case-insensitive on Windows, and case-sensitive elsewhere.
This isn't strictly right, as you can have case-sensitive things mounted on Windows or tell a Linux directory to be case-insensitive, but we can't tell when that might happen based on a lexical path as it depends on real directory properties (and might differ for different parts of the path, which is too much hassle to support).
Static variables should be initalized once instead of initializing them with
nullptr and then doing actual initialization behind if condition. Otherwise a
race condition may happen leading to undefined behaviour.
Boost::zlib is basically part of Boost::iostreams, and depending on how you configure Boost, it can either be a separate library or get embedded into iostreams.
With the third-party-but-linked-on-Boost's-website package we've been using for years, it's a separate library.
Before https://gitlab.com/OpenMW/openmw/-/merge_requests/4307, we needed to explicitly link with it as CMake wasn't handling transitive dependencies for us.
With vcpkg, it's embedded, and doesn't have its own CMake config, so we couldn't explicitly link with it even if we wanted to.
Now CMake *is* handling transitive dependencies for us, we don't even need to think about this library.
It's all automatic.
Boost::locale, on the other hand, used to be something we used directly (I think for doing UTF-16/UTF-8 conversions when dealing with Windows paths).
However, it isn't anymore, and we just didn't purge it from our CMake when we should have.
It can go.
Resolves https://gitlab.com/OpenMW/openmw/-/issues/8100
Also removes some old crud.
Hopefully the old crud is all:
* Handled automatically by CMake now we're using the modern approach.
* A hack-fix for a problem caused by not using the modern approach.
* Massively outdated so no longer necessary.
If it turns out this makes CI fail, I'll tweak things as necessary.
Changes that might not be wanted include:
* Getting rid of our BOOST_STATIC CMake option. In cases where the CMake config doesn't make the one correct choice from the build environment (i.e. because there's a choice) the CMake config exposes the option already.
However, we were forcing this on for Windows, so that might matter.
It seems to default to static on my machine even though I thought I read something suggesting otherwise, so we'll see how things go with that.
If we eventually put CMake in charge of installing dependency DLLs this will be a moot point as we won't need to care.
* Bumping the minimum version of Boost to 1.70.0, as that's the first with working CMake config.
It's from 2019, so plausibly there are distros too scared to use a library from five years ago as it can't legally drink in the US (although it could in limited quantities with parental supervision in the UK, as long as it's just something inconsequential like a single sip of beer).
I tried to fix https://gitlab.com/OpenMW/openmw/-/issues/8080 by making it so that instead of crashing, we showed an error.
In doing so, I discovered some problems with plugin sorting and the refresh button, like:
* it forgetting the non-user content files somewhere
* nothing guaranteeing that built-in content files stay at the top of the list and them only being there because the first data directory that provides them is usually the first data directory
* it forgetting the non-user content files somewhere else
* it looking like it'd forget any kind of non-user setting under certain circumstances
I fixed those problems too
To avoid implicit conversion via Normalized which creates NormalizedView from a
temporary Normalized. Mark constructors explicit on purpose so there is no
ambiguity on implicit conversion when there is an overloaded function like:
void f(const Normalized&);
void f(NormalizedView);
