CMake Action

Configure and build your CMake project using GitHub Actions. This action simplifies the workflow for configuring the build environment of a CMake project. It can also be optionally specified to build a CMake project using the cmake --build command.

Features

• Configures a CMake project using the cmake command.
• Optionally builds a CMake project using the cmake --build command.
• Supports specifying multiple CMake options directly from the action inputs.

Usage

For more information, refer to action.yml and the GitHub Actions guide.
