C-APIs
===
**XGBoost** implements a C API originally designed for various language
bindings. For detailed reference, please check xgboost/c_api.h. Here is a
demonstration of using the API.
# CMake
If you use **CMake** for your project, you can either install **XGBoost**
somewhere in your system and tell CMake to find it by calling
`find_package(xgboost)`, or put **XGBoost** inside your project's source tree
and call **CMake** command: `add_subdirectory(xgboost)`. To use
`find_package()`, put the following in your **CMakeLists.txt**:
``` CMake
find_package(xgboost REQUIRED)
add_executable(api-demo c-api-demo.c)
target_link_libraries(api-demo xgboost::xgboost)
```
If you want to put XGBoost inside your project (like git submodule), use this
instead:
``` CMake
add_subdirectory(xgboost)
add_executable(api-demo c-api-demo.c)
target_link_libraries(api-demo xgboost)
```
# make
You can start by modifying the makefile in this directory to fit your need.
