# @BLURB: common bits to run dev-util/ninja builder
|
|
# @DESCRIPTION:
|
|
# This eclass provides a single function -- eninja -- that can be used
|
|
# to run the ninja builder alike emake. It does not define any
|
|
# dependencies, you need to depend on dev-util/ninja yourself. Since
|
|
# ninja is rarely used stand-alone, most of the time this eclass will
|
|
# be used indirectly by the eclasses for other build systems (CMake,
|
|
# Meson).

# The default set of options to pass to Ninja. Similar to MAKEOPTS,
