Change these lines:

--------------------------------------------------------
# Do we have sproc?
IF(CMAKE_SYSTEM MATCHES IRIX)
   CHECK_INCLUDE_FILE("sys/prctl.h"  CMAKE_HAVE_SPROC_H)
ENDIF(CMAKE_SYSTEM MATCHES IRIX)
--------------------------------------------------------

to these:

--------------------------------------------------------
INCLUDE(CheckIncludeFiles)

# Do we have sproc?
IF(CMAKE_SYSTEM MATCHES IRIX)
   CHECK_INCLUDE_FILES("sys/types.h;sys/prctl.h"  CMAKE_HAVE_SPROC_H)
ENDIF(CMAKE_SYSTEM MATCHES IRIX)
--------------------------------------------------------

Then please submit a bug report here:

and include in the report whether this fix works.
