# The install target doesn't have a DESTDIR or INSTALL_ROOT or equivalent,
# and setting the CMAKE_INSTALL_PREFIX to $PKG/usr results in a lot of
# '/tmp/SBo/package-qtoctave' strings embedded in the qtoctave binary.
# This *could* have security implications (for example, if that binary first
# looks in the temp directory for things).  It's low risk, and would require
# someone on the system to have knowledge of how the package was built, so
# I'm being a bit "chicken little" here, but correct is always better, so I'm
# going to do this the hard way...  --rworkman
#
# Be sure to check the src/cmake_install.cmake file in version updates to
# make sure we don't miss something
