`wrksrc` is supposed to be a top-level directory. Should the build system need to be run inside a sub-directory, `build_wrksrc` should be used instead. We change to `build_wrksrc` implicitly before `do_build` and `do_install`. Let's respect `build_wrksrc` in `perl-module`.
BUILD STYLES ============ These shell snippets provide support for multiple build systems, i.e GNU configure, CMake, etc. A build style file must provide at least the following functions: - do_configure - do_build - do_install If a source package defines its own do_xxx() function, the function defined in the build style file is simply ignored.
