I need to compile an existing Open Cascade (OCC) project on my Windows machine and would like someone to guide me through every step until the build succeeds. At the moment I don’t have the development environment in place, so the job starts with installing and configuring the required toolchain—compilers, libraries, CMake, any specific SDKs—on Windows. From there, I want to move systematically through source acquisition, dependency setup, project configuration, and finally the build itself. To keep expectations crystal-clear, I will consider the job complete when: • my local environment is fully set up and documented, • the OCC project builds without errors on my computer, • I understand each major command or configuration change you introduce. Please be prepared to work live with me (screen share or similar) and follow up in writing so I can reproduce the entire process later. If you have previously automated OCC builds on Windows or published related guides, that’s a big plus—just point me to them in your bid.
