#configure ⇒ Object

Since libemf2svg v1.8.2 the source tarball no longer bundles the vcpkg tool (it moved too fast to ship as a snapshot). We bootstrap vcpkg into the work path before CMake configure runs.

#export_toolchain_to_env ⇒ Object

Downstream consumers (e.g. metanorma) sometimes patch RbConfig at runtime to point Ruby's toolchain at a known-good compiler, but those overrides live in the Ruby process and don't reach the raw cmake subprocess that mini_portile2 spawns. The result is "CMAKE_C_COMPILER not set" when the deploy environment has a stripped PATH. Mirror the resolved RbConfig toolchain into ENV so the subprocess sees the same compiler the running Ruby was built with.
