## - that person has good knownledge in the area
## - that person is able to enforce consistency in the area
## - that person may be available for giving help in the area
## - that person has push access on the repository

## <img width="28px" src="https://github.githubassets.com/favicons/favicon.svg" /> Using prebuilt binaries (GitHub Releases)
**Note**: This is the fastest option if you dont want to build from source.
1. **Go to the Releases page**
- Open the projects GitHub **Releases** page and choose the latest version.
2. **Download the correct asset for your platform**
- Pick the archive that matches your OS and architecture (for example: Windows x64 / Linux x64 / macOS arm64).
3. **Extract the archive**
- You should end up with something like:
- `include/` (headers)
- `lib/` or `bin/` (library files / DLLs)
- sometimes `cmake/` (CMake package config)
4. **Use it in your project**
### Option A: CMake package (recommended if the release includes CMake config files)
If the extracted folder contains something like `lib/cmake/omath` or `cmake/omath`, you can point CMake to it:
```cmake
# Example: set this to the extracted prebuilt folder
list(APPEND CMAKE_PREFIX_PATH "path/to/omath-prebuilt")
find_package(omath CONFIG REQUIRED)
target_link_libraries(main PRIVATE omath::omath)
```
### Option B: Manual include + link (works with any layout)
If theres no CMake package config, link it manually:
```cmake
target_include_directories(main PRIVATE "path/to/omath-prebuilt/include")
# Choose ONE depending on what you downloaded:
# - Static library: .lib / .a
# - Shared library: .dll + .lib import (Windows), .so (Linux), .dylib (macOS)
target_link_directories(main PRIVATE "path/to/omath-prebuilt/lib")
target_link_libraries(main PRIVATE omath) # or the actual library filename
```
