I am just building QGIS from scratch and noticed that while some libraries are included in the cmake files using FIND_LIBRARY, others are not. When those libraries are missing, the only error one gets is something like:

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:

I have noticed this is the case for the following libraries:
- spatialite
- spatialindex
- qwt
- qtkeychain
- qscintilla
- proj

I would expect to get something like library xy not found.
This would make it easier to build the project. I thought at first that I misconfigured something until I found out it were the libraries missing.

I hope I could help you with my feedback.

Kind regards
