vcs_tag() is slow. When the version-tag meson option is set, we can use configure_file() directly to speed up incremental builds. Before (with version-tag set to v247): ``` ‣ Running build script... [1/418] Generating version.h with a custom command real 0m0.521s user 0m0.229s sys 0m0.067s ``` After (with version-tag set to v247): ``` ‣ Running build script... ninja: no work to do. real 0m0.094s user 0m0.048s sys 0m0.022s ```
