Finaly i have find a solution with this code src :

file(
    GLOB_RECURSE
    source_files
    src/*.h
    src/*.m
    src/*.c
)

SET_SOURCE_FILES_PROPERTIES(
    ${source_files}
    PROPERTIES LANGUAGE C
)

gcc -x objective-c produce stray error with LD linking, but gcc without this
option running without LD error.
Objective-c compiler (gcc) is ok with this.
