How do I continue the building process after a soft failure such as insufficient disk space?

[YukinoHayakawa]

When building large libraries such as LLVM it's quick to fill up the disk space especially when using an SSD. Building such a giant source consumes a lot of time, I mean a lot. However, when I finally reached the installation stage, vcpkg reported insufficient disk space and aborted the process. When I try to run the same install command again it seems that it cleaned the build and started all over again... Is there any way of continuing the failed build process?? I'm already using --editable option to avoid extracting the source each time I try to install the package.

It is really painful to restart whole build (30+minutes) when I just forgot to rename license file.
Can't think of a reliable solution, but maybe set some ENV variable and check it inside vcpkg_cmake/make/etc_build? Or is there a "remove build folder" rule somewhere in vcpkg-tool?

No this is done in the vcpkg_configure_* functions. For example here:

vcpkg/scripts/cmake/vcpkg_configure_cmake.cmake
