New comment by oreo639 on void-packages repository https://github.com/void-linux/void-packages/pull/48858#issuecomment-1955117020 Comment: Alternatively, fftw (and maybe other non-`build_style=cmake` packages that makedepends on `cmake`) can be made to use cmake-bootstrap. (this is what `build_style=cmake` uses) However, `PATH="$PATH:/usr/libexec/xbps-src/bin"` needs to get explicitly defined.
