Version:            (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc 3.4.6 
OS:                Solaris

I get this cmake error on Solaris

CMake Error: Error in cmake code at
/cad4/stevee/kde-svn/kdebase/workspace/ksysguard/ksysguardd/CMakeLists.txt:25:
ADD_SUBDIRECTORY given source "SunOS" which is not an existing directory.

This is because CMakeLists.txt has:

if( ${CMAKE_SYSTEM_NAME} MATCHES "DragonFly" )
  add_subdirectory( "FreeBSD" )
  include_directories( ${CMAKE_CURRENT_SOURCE_DIR}/FreeBSD )
else( ${CMAKE_SYSTEM_NAME} MATCHES "DragonFly" )
  add_subdirectory( ${CMAKE_SYSTEM_NAME} )
  include_directories( ${CMAKE_CURRENT_SOURCE_DIR}/${CMAKE_SYSTEM_NAME} )
endif( ${CMAKE_SYSTEM_NAME} MATCHES "DragonFly" )

and ${CMAKE_SYSTEM_NAME} is "SunOS", but the directory is called Solaris. I changed CMakeLists.txt to 

if( ${CMAKE_SYSTEM_NAME} MATCHES "DragonFly" )
  add_subdirectory( "FreeBSD" )
  include_directories( ${CMAKE_CURRENT_SOURCE_DIR}/FreeBSD )
else( ${CMAKE_SYSTEM_NAME} MATCHES "DragonFly" )
  if( ${CMAKE_SYSTEM_NAME} MATCHES "SunOS" )
    add_subdirectory( "Solaris" )
    include_directories( ${CMAKE_CURRENT_SOURCE_DIR}/Solaris )
  else( ${CMAKE_SYSTEM_NAME} MATCHES "SunOS" )
    add_subdirectory( ${CMAKE_SYSTEM_NAME} )
    include_directories(${CMAKE_CURRENT_SOURCE_DIR}/${CMAKE_SYSTEM_NAME} )
  endif( ${CMAKE_SYSTEM_NAME} MATCHES "SunOS" )
endif( ${CMAKE_SYSTEM_NAME} MATCHES "DragonFly" )

which fixed it
