# Compilation Options

!!! note "Work in Progress"
    This page is a work in progress. The raw option list below is an initial dump of all compile-time defines. It still needs to be sorted into categories, have details added for options like `PCBREV` (with all possible values), and be converted into tables.

    **TODO:**
    - [ ] Sort into categories — PCB/TX model, hardware-specific, handy default setting flags, etc.
    - [ ] Add details for options like `PCBREV` with all possible values
    - [ ] Convert to a set of tables
    - [x] Clear out system-specific / autogenerated flags

Initial dump of all the compile time defines / options (`cmake -LAH` output)
