# Producer mode (VITASDK_TARGET_ONLY): the build stops once every target
# artifact exists and ships those, and only those. No gdb, no package tools,
# no SDK validation, no complete tarball -- this build is not an SDK for
# anyone, it is the target half every host will import.
#
# The host binaries it did have to build (binutils, vita-libs-gen and the
# compiler that produced the target libraries) stay behind in the build
# prefix: cmake/SysrootManifest.cmake decides what leaves.

# The tarball is created from inside this directory so it holds a single
# vitasdk/ root and no build paths. WORKING_DIRECTORY does not create it, and
# a directory that does not exist yet fails the whole command.
