# Meson only looks at the value of environment variables when options
# are defined for the first time, i.e. not on reconfiguration (see also
# https://bugs.freedesktop.org/show_bug.cgi?id=107313#c2). Consequently
# object files aren't rebuilt when such options change, e.g. "c_args" from
# "$CFLAGS". Removing all files in the build directory obviously solves that
# problem.
#
# usbredir is sufficiently small to make a full rebuild acceptable. If that
# were to change there'd be the following options:
#
# a) Use a build directory per build option set, e.g. by naming the
# directory after a hash of the various relevant environment variables.
#
# b) Explicitly pass environment variables as their target option, e.g.
# "-Dc_args=$CFLAGS". Relevant documentation:
# https://mesonbuild.com/Reference-tables.html#language-arguments-parameter-names
# https://mesonbuild.com/Reference-tables.html#compiler-and-linker-flag-environment-variables
