make target with multiple extension

How to do the following in gnu make (on mac). I have files with extendion .js and .jsx which needs to go through the build.

SRC = $(shell find src -name '*.js' -o -name '*.jsx')
LIB = $(SRC:src/%=lib/%)
lib/%.js: src/%.js
    @echo "building $@"

above only define the target for *.js files. Now, to include *.jsx, I duplicated like below (which works).

lib/%.js: src/%.js
    @echo "building $@"

lib/%.jsx: src/%.jsx
    @echo "building $@"

Anyway to combine these. I tried like

lib/%.js%: src/%.js%
    @echo "building $@"

but didn't work (make: *** No rule to make targetlib/abc.jsx', needed by build'. Stop.)

EDIT:

duplicating the build for js & jsx didn't give the same result as it causes duplication of files. The build process compile jsx file and write as .js. so, what I am trying to express is, for all files with extension.js or .jsx, run it through the build process (which renames the compiled output as .js for both js and jsx.

One way is to use a static pattern. Also make has a builtin wildcard function for simple file expansion

SRC := $(wildcard src/*.js src/*.jsx)
LIB := $(SRC:src/%=lib/%)

$(LIB): lib/%: src/%
    @echo building $@ from $^
