I did try it and it doesn't work:

---8<--- CMakeList.txt
add_custom_target (syntax-check
  COMMAND ${CXX} CHECK_SRC)

---8<---- build/src/Makefile
....
# Convenience name for target.
src/CMakeFiles/syntax-check.dir/rule:
        cd /home/olaf/Projects/programming/cpp/build && $(MAKE) -f
CMakeFiles/Makefile2 src/CMakeFiles/syntax-check.dir/rule
.PHONY : src/CMakeFiles/syntax-check.dir/rule

# Convenience name for target.
syntax-check: src/CMakeFiles/syntax-check.dir/rule
.PHONY : syntax-check

# fast build rule for target.
syntax-check/fast:
        cd /home/olaf/Projects/programming/cpp/build && $(MAKE) -f
src/CMakeFiles/syntax-check.dir/build.make
src/CMakeFiles/syntax-check.dir/build
.PHONY : syntax-check/fast


It shall be equivilanet to a 'lint' target.

Thanks,
