The documentation section
[https://www.gnu.org/software/make/manual/make.html#Utilities-in-Makefiles
16.2 Utilities in Makefiles] recommends us to use make variables such as
$(INSTALL) or $(RM) instead of writing the respective commands (install,
rm...), so as to allow users to override them with a suitable replacement.
That's what I did, I replaced all instances of "cp" with "$(CP)". I'm using it
to copy some file in the first target of a Makefile. But unfortunately it is
resolving to an empty string, which I first noticed by looking at the output.
expected:
cp /currentpath /newpath
actual:
/currentpath /newpath
Then I added a call to $(info $(CP))", which outputs an empty line.
I'm attaching the makefile.
GNU Make 4.4
Built for x86_64-redhat-linux-gnu
I'm on Fedora Workstation 38.
