### Problem description
<!-- Describe the bug that you fixed/feature request that you
implemented, or link to an existing issue describing it -->
This PR addresses issue #491 regarding the inability to open ImHex
project files (`.hexproj`) directly from various UNIX Desktop
Environments.
_NB: This PR's scope is limited to UNIX systems, as I have no access to
MacOS systems and could not find a way to automatically create file
associations on Windows._
### Implementation description
<!-- Explain what you did to correct the problem -->
In order for project files to be recognised as such, we need to create a
new MIME type. According to [RFC 6838 section
3.2](https://www.rfc-editor.org/rfc/rfc6838#section-3.2), additional
application MIME types should be defined with a vendor prefix.
_NB: This is preferred over the deprecated `x-` prefix, although RFC
6838 states that the vendor should be "a well known producer"_
This PR proposes a new mime type for ImHex project files:
`application/vnd.imhex.proj`, and associates it with the file format
`*.hexproj`.
It also implements small changes in the Arch Linux and RPM builds, in
order to correctly ship the MIME XML file during installation.
### Additional things
<!-- Anything else you would like to say -->
The implemented change has been manually tested in the following UNIX
systems and graphical environments:
- Arch Linux, with Gnome 47.2
- Arch Linux, with XFCE4
- Fedora 41 Workstation Edition, with Gnome 47.0
- Fedora 41 Plasma, with KDE Plasma 24.08.2
- Ubuntu 22.04.5, with Gnome 42.9
Which tests the functionality of the following build types:
- Arch Linux's `.zst` packages
- Debian `.deb` packages
- RPM packages
For Arch Linux and RPM packages, this has been tested to ensure that
post-installation hooks (such as regeneration of the MIME database) is
correctly executed (which it is). No further changes than those
implemented in the PR are needed.

On many distributions like AOSC OS, Alpine Linux, Arch Linux, etc.,
boost should be searched with name "Boost".
This should fix the packaging issue on AOSC OS.
### Problem description
CMake fails to find system boost when `USE_SYSTEM_BOOST` is set to ON.
### Implementation description
Find Boost.

This PR compress the debug info in the ELF files built.
This has no impact on the packages (e.g. .deb files) because they themselves have compression, but once installed in the filesystem, they this compression will be beneficial
The compression is opportunistic, happens automatically when possible
For some reason, the web version doesn't work with this (most compiler tests after this seem to fail ?) so it is disabled there

### Problem description
This PR implements some rudimentary Xcode support for building and
editing ImHex.
### Implementation description
#### Problem 1: Xcode is a multi-configuration buildsystem
The project is already rather CMake generator independent, thus it did
not need to change much to support Xcode's multi-configuration paradigm:
By default, CMake generates a `.xcodeproj` in which targets build their
artifacts into the specified `<>_OUTPUT_DIRECTORY`, postfixed by the
currently active configuration. To better fit the existing paradigm, I
instead opted ot introduce `IMHEX_MAIN_OUTPUT_DIRECTORY`. This variable
is equal to the previously used `RUNTIME_OUTPUT_DIRECTORY` when using
other generators, and is changed to include a configuration specific
_prefix_ when used with Xcode.
The result is different output directories when using Xcode, and no
changes when using any other generator.
#### Problem 2: ImHex does not support AppleClang
To allow building the codebase with Xcode, I have introduced
`IMHEX_IDE_HELPERS_OVERRIDE_XCODE_COMPILER`. Specifying this option to
`ON` will force CMake to honor the user specified compiler settings,
even when using the Xcode generator.
In practice this can be used together with the new "xcode" CMakePreset
to build the project with mainline clang using `xcodebuild`, or Xcode
itself by generating a buildsystem like so:
```
cmake --preset xcode -DCMAKE_PREFIX_PATH=/opt/homebrew/opt/llvm@17
```
This solution is of course not without flaws. The inner workings are a
particularly ugly hack, and mainline clang does not implement the
necessary extensions to allow Xcode to index the code. Regardless this
option is useful to enable future work in terms of bundling/signing
macOS applications in the "intended" way using Xcode without additional
source modifications.
#### Problem 3: Vanilla CMake + Xcode = Bad developer UX
By default, the CMake generated `.xcodeproj` is a mess. Tons of targets
are scattered about, and source files are not organized beyond grouping
them into a "Source Files" and "Header Files" group.
Even "Header Files" is missing, because the ImHex build system does not
regard private header files of libraries as sources of a target, and
Xcode does not try to guess this information.
The solution is twofold:
* Additional code has been added which organizes the targets into a neat
folder structure
* Additional code was added behind a configuration flag
`IMHEX_IDE_HELPERS_INTRUSIVE_IDE_TWEAKS` which automatically creates
source file trees in Xcode targets, and discovers the non-declared
header files via the folder convention.
### Screenshots
N/A
### Additional things
As a bonus: `IMHEX_OFFLINE_BUILD` assumes that ImHex-Patterns is cloned
into the source tree. I have added an additional fallback that tries to
locate it as a sibling folder of `${CMAKE_SOURCE_DIR}`, as this meshes
better with my filesystem setup.
The setup was tested with `CMake 3.29.2`, `Xcode 15.2`, and `llvm@17`
from homebrew.
This pull request fixes build on FreeBSD. The changes are conditioned
with `#if defined(__FreeBSD__)` preprocessor macro and they should not
affect build for other operating systems.
