I think on WIN32 its TEMP and TMP and on all UNIX I kno of its TMPDIR.

So in a first, naive attempt I would do:

if(WIN32)
   set(TMPDIR "$ENV{TEMP}")
else()
   set(TMPDIR "$ENV{TMPDIR}")
endif()

if(NOT EXISTS "${TMPDIR}")
   message(FATAL_ERROR "OOOPS, can't determine temporary directory")
endif()
