Request:

Please use "make cmake" ("make cmake3") to report build problems.

cmake with VERBOSE=1 prints way too much stuff and I find it is impossible to use.

"make cmake" filters out all the gunk to make it easy to see the relevant information:
- the compiler command lines (CFLAGS, library paths, etc)
- the compiler output (error messages, etc).

The best I can tell, cmake "VERBOSE=1" in only useful for cmake developers to debug cmake itself.

K.O.
