wxWidgets chooses target files based on the compiler id, which makes clang-cl
look under the clang_x64_lib layout.
The dependencies are built with MSVC naming/layout, and clang-cl uses the MSVC
frontend variant on Windows. Patch the generated wxWidgets config so clang-cl
loads the vc_x64_lib targets instead.
ALL_BUILD is a Visual Studio generator target. Ninja uses `all`.
When building with -x (Ninja generator), the script fails with
"ninja: error: unknown target 'ALL_BUILD'". Use the correct target
name for each generator.
The runtime DLL copy was nested under CMAKE_CONFIGURATION_TYPES, so it only ran
for multi-config generators.
Ninja single-config leaves that variable empty, which skipped copying OCCT,
GMP, MPFR, WebView2, and freetype DLLs next to the executable. Run the copy
logic for both generator styles while keeping it Windows-only.
oneTBB enables MSVC IPO/LTCG by default, which emits MSVC proprietary bitcode
objects when built with cl.exe.
lld-link cannot consume those /GL objects. Patch the TBB MSVC compiler settings
so IPO can be disabled and the dependency produces native COFF objects that both
link.exe and lld-link can consume.
clang-cl defines MSVC in CMake, but some guarded blocks apply flags or behavior
that are specific to cl.exe and should not be passed to clang-cl.
Exclude Clang from those MSVC-only branches so clang-cl follows the compatible
compiler path instead of inheriting cl.exe-only settings.
The Windows path builds url_prefix as a wide string.
MSVC accepts concatenating the narrow literals here, but clang-cl rejects the
mixed narrow/wide expression. Use wide literals so the concatenation type matches.
clang-cl is stricter about converting the T2A_ helper result in this expression.
Cast the conversion helper result explicitly to const char* so the intended
string conversion is unambiguous across MSVC and clang-cl.
LabelItemType values are used with Marker, which is std::size_t.
MSVC accepts the implicit narrowing in this path, but clang-cl diagnoses it more
strictly. Give the enum the same underlying type as Marker.
Eigen's .cast<T>() returns a lazy CwiseUnaryOp expression, not a materialized
Matrix. The distance_to_squared overload taking a nearest_point output parameter
expects a concrete Eigen::Matrix, so template deduction fails on clang-cl.
Materialize the cast into a local Vec variable before passing it.
MSVC accepted the expression directly; clang-cl correctly rejects it.
clang-cl does not instantiate BoundingBoxBase<Point, Points>::construct for
Points::const_iterator through the same transitive path accepted by MSVC.
Add the explicit instantiation so the template definition is emitted where the
clang-cl build needs it.
