Hi, "CMAKE_SYSTEM_NAME MATCHES GNU/FreeBSD" looks like it was a typo in the first place. It probably never matched anything, so I would drop it and replace with "CMAKE_SYSTEM_NAME MATCHES kFreeBSD" (rather than keep it and try to match both). If the system name in older CMake was "GNU/kFreeBSD" then the latter will still match it. Regards, -- Steven Chamberlain steven@pyro.eu.org
