Unable to build GTSAM w/ MATLAB toolbox on Windows (stable only)

[smnmsr]

Description

I'm unable to build GTSAM with the MATLAB toolbox on Windows 10. I was following the install descriptions provided in the file Install.md.

Steps to reproduce

1. Download latest release of GTSAM from here.
2. Download the boost library and add it to the PATH (boost_1_74_0, precompiled [lib64-msvc-14.2])
3. Configure and run CMake (CMakeSettings.json, cmake_out.txt)
4. Open GTSAM.sln with Visual Studio (generates warnings: "The solution already contains an item named 'examples'." and "... timing")
5. Build->Build->1 ALL_BUILD
6. The Build fails throwing 52 errors (one related to the MATLAB wrapper, the rest related to the unstable lib) see build_out.txt

Expected behavior

I expect the library to compile w/o any errors.

Environment

• MATLAB r2023b
• Visual Studio Professional 2019 (16.11.32) w/ MSVC v142
• Windows 10 Enterprise (10.0.19045)

I'd really appreciate any help! Thanks!

In the open issue I am describing how I got the toolbox installed on windows.
However, there are some workaround required (mainly when using Point3 and Vector value types) - the open issue is about making sure there is no underlying problem with the installation.

Tested on develop @ 3c2f54c (post PR #2587 merge), and the build succeeds on Windows x64 with no errors.

Environment:
OS: Windows 11 x64
Compiler: MSVC 19.51 (Visual Studio 2026 Community)
MATLAB: R2026a
CMake: 4.2.3

The build errors reported here were caused by duplicate size_t/uint64_t explicit template specializations in matlab.h that MSVC rejects on Win64. Fixed in borglab/wrap PRs #183 and #186, synced into gtsam via #2587.
