Hello,
I have a solver library (in shared format, let's say libmylib.so) that I
would like to link to deal.II. In order to do this, I checked how the METIS
library is added to libdeal_II and tried to do the same for my library,
thus I added the files configure_my_lib.cmake and FindMylib.cmake under
cmake/configure and cmake/modules, respectively.
Strange thing is that in the output of build/CMakeCache.out I find:
DEAL_II_WITH_MYLIB:BOOL=ON
MYLIB_DIR:PATH=/marconi/home/userexternal/vpaludet/projects/mylib
MYLIB_INCLUDE_DIR:PATH=/marconi/home/userexternal/vpaludet/projects/mylib/include

However, when I run "ldd build/lib/libdeal_II.so" I get:

(0x00007f4e5bdd0000)
and I don't see my library there. On the other hand, If I try to compile an
executable, let's say step-3, and run ldd on it I see that it's linked to
libdeal_II.so and also libmylib.so. My question is why my library can be
seen only by the executable and not by libdeal_II.
Thank you for helping and I'm sorry if I didn't provide enough details
about this problem. Let me know if you need more data :)
Best!!
