## Packaging Github Repos Example: libogg
|
||
|
|
### Create the CONTROL file
|
||
|
|
The `CONTROL` file is a simple set of fields describing the package's metadata.
|
||
|
|
|
||
|
|
*For libogg, we'll create the file `ports\libogg\CONTROL` with the following contents:*
|
||
|
|
```no-highlight
|
||
|
|
Source: libogg
|
||
|
|
Version: 1.3.3
|
||
|
|
Description: Ogg is a multimedia container format, and the native file and stream format for the Xiph.org multimedia codecs.
|
||
|
|
```
|
||
|
|
|
||
|
|
### Create the portfile
|
||
|
|
`portfile.cmake` describes how to build and install the package. First we include `vcpkg_common_functions` to give us utilities for carrying this out:
|
||
|
|
|
||
|
|
```no-highlight
|
||
|
|
include(vcpkg_common_functions)
|
||
|
|
```
|
||
|
|
|
||
|
|
Now we download the project from Github with [`vcpkg_from_github`](../maintainers/vcpkg_from_github.md):
|
||
|
|
|
||
|
|
```no-highlight
|
||
|
|
vcpkg_from_github(
|
||
|
|
OUT_SOURCE_PATH SOURCE_PATH
|
||
|
|
REPO xiph/ogg
|
||
|
|
REF v1.3.3
|
||
|
|
SHA512 0bd6095d647530d4cb1f509eb5e99965a25cc3dd9b8125b93abd6b248255c890cf20710154bdec40568478eb5c4cde724abfb2eff1f3a04e63acef0fbbc9799b
|
||
|
|
HEAD_REF master
|
||
|
|
)
|
||
|
|
```
|
||
|
|
|
||
|
|
The important parts to update are `REPO` for the GitHub repository path, `REF` for a stable tag/commit to use, and `SHA512` with the checksum of the downloaded zipfile (you can get this easily by setting it to `1`, trying to install the package, and copying the checksum).
|
||
|
|
|
||
|
|
Finally, we configure the project with CMake, install the package, and copy over the license file:
|
||
|
|
|
||
|
|
```no-highlight
|
||
|
|
vcpkg_configure_cmake(
|
||
|
|
SOURCE_PATH ${SOURCE_PATH}
|
||
|
|
PREFER_NINJA
|
||
|
|
)
|
||
|
|
vcpkg_install_cmake()
|
||
|
|
file(INSTALL ${SOURCE_PATH}/COPYING DESTINATION ${CURRENT_PACKAGES_DIR}/share/libogg RENAME copyright)
|
||
|
|
```
|
||
|
|
|
||
|
|
Check the documentation for [`vcpkg_configure_cmake`](../maintainers/vcpkg_configure_cmake.md) and [`vcpkg_install_cmake`](../maintainers/vcpkg_install_cmake.md) if your package needs additional options.
|
||
|
|
|
||
|
|
Now you can run `vcpkg install libogg` to build and install the package.
|
||
|
|
|
||
|
|
### Suggested example portfiles
|
||
|
|
In the `ports\` directory are many libraries that can be used as examples, including many that are not based on CMake.

||
|
|
- Header only libraries
|
||
|
|
- rapidjson
|
||
|
|
- range-v3
|
||
|
|
- MSBuild-based
|
||
|
|
- cppunit
|
||
|
|
- mpg123
|
||
|
|
- Non-CMake, custom buildsystem
|
||
|
|
- openssl
