Dominik,
Looks Like I'll need to work on documentation! That OPTION is intended to
work with the EXTERNAL_PROJECT of CMake. Here is the relevant CMake code:
INCLUDE (ExternalProject)
OPTION (HDF5_ALLOW_EXTERNAL_SUPPORT "Allow External Library Building" "NO")
OPTION (ZLIB_USE_EXTERNAL "Use External Library Building for ZLIB" 0)
OPTION (SZIP_USE_EXTERNAL "Use External Library Building for SZIP" 0)
IF (HDF5_ALLOW_EXTERNAL_SUPPORT MATCHES "SVN" OR HDF5_ALLOW_EXTERNAL_SUPPORT
MATCHES "TGZ")
SET (ZLIB_USE_EXTERNAL 1)
SET (SZIP_USE_EXTERNAL 1)
IF (HDF5_ALLOW_EXTERNAL_SUPPORT MATCHES "SVN")
SET (ZLIB_URL ${ZLIB_SVN_URL})
SET (SZIP_URL ${SZIP_SVN_URL})
ELSEIF (HDF5_ALLOW_EXTERNAL_SUPPORT MATCHES "TGZ")
IF (NOT TGZ_PATH)
SET (TGZ_PATH ${HDF5_SOURCE_DIR})
ENDIF (NOT TGZ_PATH)
SET (ZLIB_URL ${TGZ_PATH}/${ZLIB_TGZ_NAME})
SET (SZIP_URL ${TGZ_PATH}/${SZIP_TGZ_NAME})
ENDIF (HDF5_ALLOW_EXTERNAL_SUPPORT MATCHES "SVN")
ENDIF (HDF5_ALLOW_EXTERNAL_SUPPORT MATCHES "SVN" OR HDF5_ALLOW_EXTERNAL_SUPPORT
MATCHES "TGZ")
So if you just want to setup the lib and include paths, don't use these OPTIONS.
