/Me too. ;-)

This would be possible (and more general, i.e. also for Makefile-based
projects), if one could use some variables in the build settings
(command and working directory), like currently open document name and
directory.
I have suggested this in the context of running "make" in the current
directory, which for me would be the same use case as compiling a single
.cpp file:
