An action for building CMake projects.

There are two ways of using this action, (1) to build the repository where the workflow is stored, or (2) to clone a CMake project into the workspace and build it.

To clone and build at the same time:

workflow "compile a cmake project" {
  on = "push"
  resolves = "build"
}

action "build" {
  uses = "popperized/cmake@master"
  args = "install"
  env = {
    CMAKE_GIT_REPO = "https://github.com/bast/cmake-example",
    CMAKE_GIT_REF = "dev",
    CMAKE_INSTALL_DEPS_SCRIPT = "scripts/install_deps.sh",
    CMAKE_FLAGS = "-DCMAKE_INSTALL_PREFIX:PATH=/tmp/foo",
    CMAKE_BUILD_THREADS = "8"
  }
}

Or to run for an existing folder:

workflow "compile a cmake project" {
  on = "push"
  resolves = "build"
}

action "build" {
  uses = "popperized/cmake@master"
  args = "install"
  env = {
    CMAKE_PROJECT_DIR = "./",
    CMAKE_FLAGS = "-DCMAKE_INSTALL_PREFIX:PATH=$GITHUB_WORKSPACE/install",
    CMAKE_CLEAN = 1
  }
}

• CMAKE_GIT_REPO optional a string containing a valid Git URL of a repo. This repo is assumed to be a CMake project, which is cloned into the workspace and built. Either this or CMAKE_PROJECT_DIR is expected.

• CMAKE_GIT_REF optional the Git REF intended to be checked out. If not given, the default branch is checked out.

• CMAKE_PROJECT_DIR optional the path to the folder in the workspace containing the CMake project to build. Either this or CMAKE_GIT_REPO is expected.

• CMAKE_INSTALL_DEPS_SCRIPT optional The path to an executable bash script that is invoked prior to running CMake which can be used to install build dependencies (base image is Debian 10).

• CMAKE_FLAGS optional a string containing flags that are passed to the cmake command. Empty string by default.

• CMAKE_CLEAN optional remove the build/ folder prior to executing cmake. By default (when this variable is not set), the build/ is left intact.

• CMAKE_BUILD_THREADS optional number of threads used to build the project; passed to make via the -j flag. By default this is grep processor /proc/cpuinfo | wc -l.
