mongodb - Undefined reference to symbol error when linking Mongo C driver static library

Question

I'm trying to build a program using the Mongo C driver. My CMake configuration includes this:

include_directories("/usr/local/include/libmongoc-1.0")
include_directories("/usr/local/include/libbson-1.0")
...
SET (STATIC_LIBS
    ...
    libmongoc-static-1.0.a
    libbson-static-1.0.a
)

TARGET_LINK_LIBRARIES(myapp ${STATIC_LIBS})

Compile stage goes fine (so it seems that includes are correctly found), but when the linking stage takes place I get this error:

/usr/bin/ld: /usr/local/lib/libmongoc-static-1.0.a(mongoc-counters.c.o): undefined reference to symbol 'shm_unlink@@GLIBC_2.2.5'

It seems it correctly find the static library file but something in it doesn't like it...

Somebody has found a similar error? Is there any known solution?

Some additional info about my system:

• gcc version: 6.3.0
• Mongo C driver version: 1.16.0
• MongoDB version: 4.4.1
• Operating system: Debian 9.3

Thanks!
