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
analyz         


        

Answer 1

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.

Answer 2

I found a way:

function(add_clang_static_analysis target)
    get_target_property(SRCs ${target} SOURCES)
    add_library(${target}_analyze OBJECT EXCLUDE_FROM_ALL ${SRCs})
    set_target_properties(${target}_analyze PROPERTIES
                          COMPILE_OPTIONS "--analyze"
                          EXCLUDE_FROM_DEFAULT_BUILD true)
endfunction()

Combining clang's plist files (which get extension .o this way) into a report is still open ($<TARGET_OBJECTS:objlibtarget>?).
