Skia's authoritative build system is moving to Bazel. For users needing to use other build system, this tool will export a subset of the Bazel build targets to other build systems.
This is not meant for any purpose beyond development.
At the root level of the Skia workspace:
bazel build //bazel/exporter_tool bazel-bin/bazel/exporter_tool/exporter_tool_/exporter_tool -proj_name=Skia -rule='//:skia_public'
This will write to a single CMakeLists.txt file a valid CMake project with targets to build the artifacts covered by the Bazel //:skia_public target and all dependent targets.
//:skia_public rule is supported. Other rules may work.
