CMake add target for invoking clang analyzer

Question

I'd basically like to achieve the same as http://blog.alexrp.com/2013/09/26/clangs-static-analyzer-and-automake, but with CMake.

analyze_srcs = foo.c
analyze_plists = $(analyze_srcs:%.c=%.plist)
CLEANFILES = $(analyze_plists)

$(analyze_plists): %.plist: %.c
  @echo "  CCSA  " $@
  @$(COMPILE) --analyze $< -o $@

analyze: $(analyze_plists)
.PHONY: analyze

So you can run

make analyze
make clean

I guess I need to use add_custom_command/add_custom_target and somehow change the "object file" extension just for that target.

Afterwards get a list of the generated files to perhaps pass them to a script for combining them into 1 output file.

Can anyone point me in the right direction?

You can use scan-build when running cmake.

scan-build cmake /path/to/source
scan-build make

scan-build sets the CC and CXX environment variables which are picked up by cmake.
