# [Blueline] Improving build steps for icon-exclaim
###### tags: `cycle 19`
<!-- Add the tag for the current cycle number on top -->
- Shaped by: Christoph, Abishek, Jonas, Will
- Appetite (FTEs, weeks):
- Developers: <!-- Filled in at the betting table unless someone is specifically required here -->
## Problem
## Appetite
<!-- Explain how much time we want to spend and how that constrains the solution -->
- Merge: 1 cycle
- nlohmann: 2 hours
- install step repetition: 1 week
- hard coded build type: 2 hours
## Solution
<!-- The core elements we came up with, presented in a form that’s easy for people to immediately understand -->
## Rabbit holes
<!-- Details about the solution worth calling out to avoid problems -->
## No-gos
<!-- Anything specifically excluded from the concept: functionality or use cases we intentionally aren’t covering to fit the ## appetite or make the problem tractable -->
## Progress
<!-- Don't fill during shaping. This area is for collecting TODOs during building. As first task during building add a preliminary list of coarse-grained tasks for the project and refine them with finer-grained items when it makes sense as you work on them. -->
