libcifpp-10.0.4 fails to build if -DBUILD_SQLITE_INTERFACE=no

[pacho2]

I need to build it with -DBUILD_SQLITE_INTERFACE enabled, otherwise, build fails with these errors:

Thanks for your help

It seems that building of tests and examples needs SQLite too:

cif++/cql.hpp is only added to project_headers if BUILD_SQLITE_INTERFACE is ON, i.e. does not get installed if BUILD_SQLITE_INTERFACE is OFF.

but cif++.hpp does #include "cif++/cql.hpp" in any case.

this seems WRONG.
