do you know if it is possible to feed multiple wildcards to a rule, like so:
%.o: %.cpp %.ui

and then we can check if a .ui file exist and call UIC before calling
CXX for a file with the same name in that rule, removing the rule:
ui_%.h: %.ui .uic

my idea is that changes in specific .ui files should only update
specific .o files and not all .o files. not sure that will work in
general.

also any idea where this call comes from:
g++ -Wall -g     -c -o qthelper.o qthelper.cpp
and why adding $(UIC_HEADERS) in the dependencies fixes it? i've tried
disabling all CXX calls, but it still triggers.
