A variable definition in a Makefile consists of a variable name
and its defition. Both are separated by the equality sign =.
No quoting is applied to the definition by this function. Currently, both variable and definition are required to be character values of length one.
Use the
c function or the + operator
to append definitions to groups and Makefiles.
