Unit / Geolocation / Placement are schema-agnostic IFC helpers ported
from ifcopenshell.util.{unit,geolocation,placement}. Nothing about
them is viewer-specific: pure IfcParse + Eigen, no Qt, no IfcGeom, no
renderer. Living under src/ifcviewer/ implies an unwanted dependency
direction every time a non-viewer caller (test_federation, the bonsai
SettingsView georef readout, a future standalone IFC tool) wants to
use them.
Move them to a new `src/ifcutil/` static lib (IfcUtil). The lib has
PUBLIC `target_include_directories(${CMAKE_CURRENT_SOURCE_DIR})` so
callers that link IfcUtil can keep `#include "Unit.h"` etc. without
relative-path adjustments — the include dir propagates transitively
via IfcViewer's PUBLIC link.
## Changes
* `git mv src/ifcviewer/{Geolocation,Placement,Unit}.{h,cpp}
→ src/ifcutil/` (history follows the rename).
* `src/ifcutil/CMakeLists.txt`: IfcUtil static lib, PUBLIC links
IfcParse + Eigen3::Eigen, PUBLIC include dir.
* `cmake/CMakeLists.txt`: `add_subdirectory(../src/ifcutil ifcutil)`
before ifcviewer/ so the link target exists when IfcViewer's
CMakeLists runs.
* `src/ifcviewer/CMakeLists.txt`: IfcUtil added to IfcViewer's PUBLIC
link_libraries.
* `src/ifcviewer/tests/CMakeLists.txt`: test_federation drops the
explicit `${IFCVIEWER_SRC}/{Unit,Geolocation,Placement}.cpp`
source list and links `IfcUtil` instead (matches how production
code resolves the symbols).
* `src/bonsaiviewer/modules/models/SettingsView.cpp`: the two
explicit `#include "../../../ifcviewer/{Geolocation,Unit}.h"`
paths swap to `../../../ifcutil/…`. All other callers use bare
`#include "Unit.h"` style and continue to work via the propagated
include dir.
## Verification
* `ninja -C build-viewer` builds clean: IfcUtil + IfcViewer +
IfcViewerMinimal + BonsaiViewer + all four pre-existing
ifcviewer tests + the two from-wgpu tests.
* `test_federation` runs green: 226 assertions in 22 test cases
pass with IfcUtil linked instead of the explicit-source compile.
* `git log --follow` traces e.g. `Geolocation.cpp` back through the
rename to its prior location in src/ifcviewer/.

IfcOpenShell
IfcOpenShell is an open source (LGPL) software library for working with Industry Foundation Classes (IFC). Complete parsing support is provided for IFC2x3 TC1, IFC4 Add2 TC1, IFC4x1, IFC4x2, and IFC4x3 Add2. Extensive geometric support is implemented for the IFC releases IFC2x3 TC1 and IFC4 Add2 TC1. Extending with support for arbitrary IFC schemas is possible at compile-time when using C++ and at run-time when using Python.
In addition to a C++ and Python API, IfcOpenShell comes with an ecosystem of tools, notably including IfcConvert (an application to convert IFC models to other formats), Bonsai (an add-on to Blender providing a graphical IFC authoring platform), and many other libraries, CLI apps, and more. Support is also provided for auxiliary standards such as BCF and IDS.
