Is the idea here to be able to run OpenROAD with Bazel, in a fine-grained and hermetic way? That would be very cool, but it's kind of a big task. Here is a super rough list of packages that OpenROAD consists of and their dependencies. I made it just to get a rough idea of the size of the project, it's probably not entirely accurate:

• OpenSTA: Tcl, swig, bison, flex, libz, cudd
• OpenDB: Tcl, swig, def, lef, zlib
• init_fp: Small and no deps
• ioplacer: Opendb, boost, tcl, zlib, opendb
• pdn: tcl scripts, not sure about deps
• tapcell
• Innovus
• RePlace: Replace, Flute, OpenSTA, Eigen, Cimg, OpenROAD (?)
• Cimg: No-dep library
• Resizer: def, lef, flute, opensta, cudd, tcl
• Cudd: It’s small and dependency free
• Flute: It’s small and dependency free
• Lef: Depends only on zlib and bison
• Def: Depends only on zlib and bison
• OpenDP: Swig, tcl, def, lef
• TritonCTS: LEMON, Swig, opendb
• LEMON: Header-only, no deps
• FastRoute: Opendb, flute3, tcl, swig, zlib, boost
• TritonRoute: Def, lef, zlib, bison, boost
• Magic
• Netgen
• Swig
