#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 -- unless we're targeting musl, in which case vcpkg has no public binary cache for arm64-linux-musl / x64-linux-musl and would compile every dependency from source (hours). For musl we use the distribution's own -dev packages (freetype, fontconfig, etc.) via pkg-config instead.

#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.

#use_system_libs? ⇒ Boolean

Musl builds link against the distro's own -dev packages (freetype, fontconfig, libxml2, libpng) via pkg-config. This sidesteps vcpkg's lack of a public binary cache for musl triplets, which otherwise forces from-source compiles that exceed CI timeouts.
