Subject: [PATCH] doxygen: fix reproducibility issue of doxygen-src

[ snip of CMakeLists.txt ]
BISON_TARGET(constexp
             ${CMAKE_CURRENT_LIST_DIR}/constexp.y
             ${GENERATED_SRC}/ce_parse.cpp
             COMPILE_FLAGS "${YACC_FLAGS}")
[ end of snip ]

bison embeds full paths in its generated headers, eg:
bison -o /full/build/path/generated/example.cpp ...
The header will include:
 #ifndef YY_FULL_BUILD_PATH_GENERATED_MSCGEN_LANGUAGE_HPP_INCLUDED
 #define YY_FULL_BUILD_PATH_GENERATED_MSCGEN_LANGUAGE_HPP_INCLUDED

This make doxygen-src not reproducible, fix by replacing full build path
