cc390f11ee feat(build): build the missing dependencies from the main CMake configure (#15373)
* fix(deps): build the dependencies from scratch with clang-cl

Six dependencies fail once the superbuild compiles them with clang-cl instead
of cl:

- OpenSSL never goes through CMake. Its VC-WIN64A makefile only works with cl,
  and an unquoted clang-cl path with spaces produces no .obj files at all, so
  the lib step dies with LNK1181. Pin the upstream toolchain.
- Boost.Container's bundled dlmalloc passes int* to the Interlocked API. cl
  warns, clang rejects it.
- curl 7.75's configure probes rely on C laxness clang rejects. The results
  flip and nonblock.c ends up in the AmigaOS IoctlSocket branch.
- OCCT installs RelWithDebInfo into bini/libi while find_package looks in lib.
  It also prepends -Wl,-s to the shared linker flags for every Clang build,
  which the MSVC-style linker gets as an argument it does not know. Both
  patched hunks sit inside if (MSVC) in the OCCT sources.
- wxWidgets lands in lib/clang_x64_lib, so wxWidgetsConfig.cmake falls back to
  the layout that exists instead of assuming vc_x64_lib. It tries the derived
  path first, so a cl-built tree consumed by clang-cl keeps resolving the way
  it does today. The patch step also resets the one file it touches, so it can
  run again after an interrupted build or after the patch itself changed.
- wxInspector goes through FindwxWidgets, which only searches lib/vc*_lib
  because _WX_TOOL is hardcoded to vc. It now gets the root and lib dir
  derived the same way wxWidgetsConfig.cmake derives them.

Eigen is the seventh, and it breaks on the generator rather than the compiler.
Its test, lapack and blas/testing subdirectories all call
enable_language(Fortran), and they default to ON because the dependency
configures as its own top-level project. Whether that hurts depends on what
CMake finds: the Visual Studio generator supports no Fortran and finds nothing,
clang-cl sits next to the LLVM toolset's flang and works, while MSVC with Ninja
finds Strawberry Perl's MinGW gfortran, which this build already requires for
OpenSSL, and hands it the MSVC-style /machine:x64 that MinGW's ld reads as a
missing input file. The configure dies there and takes every dependency still
in flight with it. Only the headers are consumed here, so the three subprojects
are off.

* fix(deps): honor the superbuild's generator and compiler in sub-builds

orcaslicer_add_cmake_project pinned every dependency sub-build to the Visual
Studio generator whenever MSVC was true, which is also true for clang-cl. That
generator selects its compiler by toolset and ignores the CMAKE_C_COMPILER and
CMAKE_CXX_COMPILER this file already forwards, so the dependencies were built
with cl.exe no matter which generator or compiler the superbuild was given.

Key the three affected decisions on the generator instead: which generator the
sub-builds use, whether CMAKE_BUILD_TYPE is forwarded, and /m versus -j. A
Visual Studio superbuild is unchanged, so the default path and CI behave
exactly as they do today.

build_release_vs.bat now accepts -l to select clang-cl, alongside the existing
-x for Ninja, so the generator and the compiler can be chosen independently. On
the Visual Studio generator -l reaches the slicer only, through the ClangCL
toolset, because the dependency sub-builds have no toolset to inherit; a deps
build in that combination says so rather than quietly using MSVC.

* fix(deps): use upstream wxWidgets compiler layout fix

The compiler-prefix layout fix now comes from SoftFever/Orca-deps-wxWidgets#7, so remove the duplicated local patch and apply step.

* fix(deps): stop Assimp enabling ccache on the RC rule

ASSIMP_BUILD_USE_CCACHE defaults on and applies the launcher through the
global RULE_LAUNCH_COMPILE property, so it wraps the resource-compiler rule
as well. Under Ninja that rule goes through cmcldeps, which does not survive
being launched by ccache, and the build fails with clang-cl reporting /fo as
a missing file.

The superbuild already forwards CMAKE_<LANG>_COMPILER_LAUNCHER, which CMake
applies per language and so keeps clear of the RC rule.

dc5897d7b5 Update eigen to v5.0.1 and libigl to v2.6.0. (#11311)
* Update eigen from v3.3.7 to v5.0.1.

This updates eigen from v3.3.7 released on  December 11, 2018-12-11 to v5.0.1
released on 2025-11-11. There have be a large number of bug-fixes,
optimizations, and improvements between these releases. See the details at;

https://gitlab.com/libeigen/eigen/-/releases

It retains the previous custom minimal `CMakeLists.txt`, and adds a
README-OrcaSlicer.md that explains what version and parts of the upstream
eigen release have been included, and where the full release can be found.

* Update libigl from v2.0.0 (or older) to v2.6.0.

This updates libigl from what was probably v2.0.0 released on 2018-10-16 to
v2.6.0 released on 2025-05-15. It's possible the old version was even older
than that but there is no version indicators in the code and I ran out of
patience identifying missing changes and only went back as far as v2.0.0.

There have been a large number of bug-fixes, optimizations, and improvements
between these versions. See the following for details;

https://github.com/libigl/libigl/releases

I retained the minimal custom `CMakeLists.txt`, added `README.md` from the
libigl distribution which identifies the version, and added a
README-OrcaSlicer.md that details the version and parts that have been
included.

* Update libslic3r for libigl v2.6.0 changes.

This updates libslic3r for all changes moving to eigen v5.0.1 and libigl
v2.6.0. Despite the large number of updates to both dependencies, no changes
were required for the eigen update, and only one change was required for the
libigl update.

For libigl, `igl::Hit` was changed to a template taking the Scalar type to
use. Previously it was hard-coded to `float`, so to minimize possible impact
I've updated all places it is used from `igl::Hit` to `igl::Hit<float>`.

* Add compiler option `-DNOMINMAX` for libigl with MSVC.

MSVC by default defines `min(()` and `max()` macros that break
`std::numeric_limits<>::max()`. The upstream cmake that we don't include
adds `-DNOMINMAX` for the libigl module when compiling with MSVC, so we need
to add the same thing here.

* Fix src/libslic3r/TriangleMeshDeal.cpp for the unmodified upstream libigl.

This fixes `TriangleMeshDeal.cpp` to work with the unmodified upstream
libigl v2.6.0. loop.{h,cpp} implementation.

This file and feature was added in PR "BBS Port: Mesh Subdivision" (#12150)
which included changes to `loop.{h,cpp}` in the old version of libigl. This PR
avoids modifying the included dependencies, and uses the updated upstream
versions of those files without any modifications, which requires fixing
TriangleMeshDeal.cpp to work with them.

In particular, the modifications made to `loop.{h,cpp}` included changing the
return type from void to bool, adding additional validation checking of the
input meshes, and returning false if they failed validation. These added
checks looked unnecessary and would only have caught problems if the input
mesh was very corrupt.

To make `TriangleMeshDeal.cpp` work without this built-in checking
functionality, I removed checking/handling of any `false` return value.

There was also a hell of a lot of redundant copying and casting back and forth
between float and double, so I cleaned that up. The input and output meshs use
floats for the vertexes, and there would be no accuracy benefits from casting
to and from doubles for the simple weighted average operations done by
igl::loop(). So this just uses `Eigen:Map` to use the original input mesh
vertex data directly without requiring any copy or casting.

* Move eigen from included `deps_src` to externaly fetched `deps`.

This copys what PrusaSlicer did and moved it from an included dependency under
`deps_src` to an externaly fetched dependency under `deps`. This requires
updating some `CMakeList.txt` configs and removing the old and obsolete
`cmake/modules/FindEigen3.cmake`. The details of when this was done in
PrusaSlicer and the followup fixes are at;

* 21116995d7
* https://github.com/prusa3d/PrusaSlicer/issues/13608
* https://github.com/prusa3d/PrusaSlicer/pull/13609
* e3c277b9ee

For some reason I don't fully understand this also required fixing
`src/slic3r/GUI/GUI_App.cpp` by adding `#include <boost/nowide/cstdio.hpp>` to
fix an `error: ‘remove’ is not a member of ‘boost::nowide'`. The main thing I
don't understand is how it worked before. Note that this include is in the
PrusaSlicer version of this file, but it also significantly deviates from what
is currently in OrcaSlicer in many other ways.

* Whups... I missed adding the deps/Eigen/Eigen.cmake file...

* Tidy some whitespace indenting in CMakeLists.txt.

* Ugh... tabs indenting needing fixes.

* Change the include order of deps/Eigen.

It turns out that although Boost includes some references to Eigen, Eigen also
includes some references to Boost for supporting some of it's additional
numeric types.

I don't think it matters much since we are not using these features, but I
think technically its more correct to say Eigen depends on Boost than the
other way around, so I've re-ordered them.

* Add source for Eigen 5.0.1 download to flatpak yml config.

* Add explicit `DEPENDS dep_Boost to deps/Eigen.

I missed this before. This ensures we don't rely on include orders to make
sure Boost is installed before we configure Eigen.

* Add `DEPENDS dep_Boost dep_GMP dep_MPFR` to deps/Eigen.

It turns out Eigen can also use GMP and MPFR for multi-precision and
multi-precision-rounded numeric types if they are available.

Again, I don't think we are using these so it doesn't really matter, but it is
technically correct and ensures they are there if we ever do need them.

* Fix deps DEPENDENCY ordering for GMP, MPFR, Eigen, and CGAL.

I think this is finally correct. Apparently CGAL also optionally depends on
Eigen, so the correct dependency order from lowest to highest is GMP, MPFR, Eigen, and CGAL.
