CMake failure with LIB_OFX OFF

[Sumit Bhardwaj]

After pulling the latest master, I was able to make and make check using
autotools. However, cmake failed.

With the command:
>cmake -D WITH_AQBANKING=OFF -D WITH_OFX=OFF -G Ninja ../gnucash/ && ninja
check && ninja install

The error at the end is:
