While changing FindSqlite.cmake to build a test program to check the
version would
address your concern here, the file has WIN32 logic I'd rather not mess with and
specifically does not help the issue raised in the following paragraph
of my email
(which appears to have been cut from your reply):

] Unfortunately the SQLITE_INCLUDE_DIR extracted is also passed back up
] the build system to be used later in an include_directories() call in
] qsqlite/CMakeLists.txt
]
] So, I now propose to:
] - add additional sqlite3 version check logic to wip/akonadi to be used
] only in the pkg-config case
] - change NetBSD's sqlite3.pc file to specify explicit includedir & libdir

Also, to re-iterate a point raised earlier in this thread:

cmake appears to provide a documented interface for extracting values
from pkg-config
http://www.cmake.org/cmake/help/cmake-2-8-docs.html#module:FindPkgConfig
including ..._LIBRARY_DIRS and ..._INCLUDE_DIRS, and _VERSION

If you expect developers using cmake to not use that interface then I
think that is
a whole different discussion and not one usefully discussed on a pkgsrc list...
