libad_map_opendrive_reader.so: undefined reference to `pugi::xml_named_node_iterator::operator++()'

[tvsrr]

I have included the library in all the cpp files "pugixml.hpp"; yet I see this when I am trying to build the file.

Hmm, seems like the linker might not actually be linking to pugixml. So you might want to check the actual detailed build output within the log/latest/* folder.
But as the ad_map_opendrive_reader.so has already the issue, it doesn't help to just not build osm_to_adm binary (which might not be required as it's a tool). You might be able to debug more by switching to the build/ad_map_opendrive_reader directory and find out what actually is listed as linked libraries if you call e.g. "ccmake ." there. Or just manually inspect the build/ad_map_opendrive_reader/CMakeCache.txt file there. What is there listed as PUGIXML_LIBRARIES? I believe that PUGIXML_INCLUDE_DIR should somehow be listed correctly otherwise it would even not compile... That's e.g. what listed on my Ubunut 16.04 machine in this file after

//Path to a file.
PUGIXML_INCLUDE_DIR:PATH=/usr/include

//Path to a library.
PUGIXML_LIBRARIES:FILEPATH=/usr/lib/x86_64-linux-gnu/libpugixml.so

And when I call
$> ldd libad_map_opendrive_reader.so

linux-vdso.so.1 =>  (0x00007fff9656c000)
libpugixml.so.1 => /usr/lib/x86_64-linux-gnu/libpugixml.so.1 (0x00007f7d0f1ef000)
libproj.so.9 => /usr/lib/x86_64-linux-gnu/libproj.so.9 (0x00007f7d0ef94000)
libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f7d0ebb1000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f7d0e8a8000)
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f7d0e690000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f7d0e2c6000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f7d0e0a9000)
/lib64/ld-linux-x86-64.so.2 (0x00007f7d0f852000)

I believe in your case something went wrong...
But usually the build should abort on CMake configure if it is not found.
according to map/ad_map_opendrive_reader/CMakeLists.txt:
#pugixml
find_library(PUGIXML_LIBRARIES
NAMES pugixml
)
find_path(PUGIXML_INCLUDE_DIR
NAMES pugixml.hpp
)
if((NOT PUGIXML_LIBRARIES) OR (NOT PUGIXML_INCLUDE_DIR))
message(FATAL "Dependency pugixml not found!")
endif()

I guess, you already tried to delete the build directory and triggered a rebuild to ensure that there was not some kind of incomplete build as root cause....

Issue solved when pugixml share object creation is enabled in the cmakelists.txt
