I’m trying to figure out how to learn to use FILE\_SET after watching some talks but I’m not sure how even after reading documentation.

cmake\_minimum\_required(VERSION 4.1)

project(TradingEngine)

find\_package(GTest REQUIRED)

find\_package(benchmark REQUIRED)

add\_library(TradingEngineLib STATIC)

target\_sources(

```auto
TradingEngineLib

PUBLIC

    FILE_SET HEADERS

```

)

add\_executable(

```auto
TradingEngine

src/main.cpp

```

)

target\_link\_libraries(

```auto
TradingEngine

TradingEngineLib

```

)

Thank you!
