Now that the DOS SDL supports CMake, this is a much better option that
`configure`, because it lets us easily test out local changes to SDL,
e.g.:
```bash
cmake -S. -Bbuild-dos -DCMAKE_TOOLCHAIN_FILE=CMake/platforms/djcpp.toolchain.cmake \
-DTARGET_PLATFORM="dos" -DCMAKE_BUILD_TYPE=Release -DBUILD_TESTING=OFF \
-DFETCHCONTENT_SOURCE_DIR_SDL2="${HOME}/diasurgical-SDL"
```
Ubuntu 20.04 is going EOL in May.
Ubuntu 22.04 CMake is 3.22.
Debian stable CMake is 3.25.
Debian oldstable (EOL in 2026) has CMake 3.25 in bullseye-backports.
Collects transitive object library dependencies in the topological order
and adds cycle detection.
Now transitive dependencies are actually all linked.
This does not fully address the issue of most everything
being a giant library but it's a start.
Note that the libraries are OBJECT libraries, so they
may (and currently do) contain references to missing
symbols.
Also fixes the implementation of transitive dependency
support for OBJECT libraries.
This mod renders a clock in the top-right corner
and is always available (disabled by default).
It is useful to have a mod available by default
as we work on mod support.
On CMake v3.28+, `EXCLUDE_FROM_ALL` is supported natively as an argument
to `FetchContent_Declare`.
On CMake v3.30+, `FetchContent_Populate`, which we use to polyfill
`EXCLUDE_FROM_ALL` support for older versions of CMake, is deprecated
and triggers a noisy warning.
Avoids the warning by using the native `EXCLUDE_FROM_ALL` support on
CMake v3.28+.
1. Updates the Dockerfile to the same image and flags as the CI.
2. Sets `-O2` as the default CMake Release flag rather than passing it
in a custom way.
Our implementation has a more modern interface and only
supports the features that we care about.
It always outputs `\n` as newlines and does not output BOM.
The modern interface eliminates awkward `c_str()/data()` conversions.
This implementation preserves comments and the file order of sections
and keys. New keys are written in insertion order.
We now also support modifying and adding default comments,
which may be a useful thing to do for the especially tricky
ini options (this PR doesn't add any but adds the ability to do so).
Sadly, this increases the RG99 binary size by 24 KiB.
I'm guessing this is because the map implementation generates
quite a bit of code.
Note that while it might seem that using `std::string` for every key and
value would do a lot of allocations, most of these strings are
small and thus benefit from Small String Optimization (= no allocations).
