Someone (perhaps you?) created a GitHub issue for a similar problem recently, and I responded there:

When building from the latest 1.14.0 source code, I encountered numerous LNK2001… errors. Here are my development environment details: .NET version: 8.0.404 CMake version: 3.26.3 Visual Studio: 2022 I followed these steps: 1. `dotnet publish Reinterop~ -o .` 2. Opened Unity. 3. `cmake -B build -S . -DCMAKE_BUILD_TYPE=Debug` 4. `cmake --build build -j14 --target install --config Debug` After completing these steps, I received multiple LNK2001 errors. Some examples include: Could you provide any insights into why this might be occurring? Thank you in advance for your assistance. `s2.lib(s2coords.cc.obj) : error LNK2001: unresolved external symbol "public: __cdecl absl::lts_20240722::log_internal::LogMessageFatal::LogMessageFatal(char
