Dynamically search for lib or lib64 path

[jandrej]

On OpenSuse libmesh decides to install the pkgconfig files into

${LIBMESH_DIR}/lib64/pkgconfig

instead of

${LIBMESH_DIR}/lib/pkgconfig

which is ok, but we need to check for that in order to get that working. @mechiluca can you check if you can manage to edit the CMakeLists.txt so it checks for that? The corresponding code is

# libMesh
if (LIBMESH_DIR)
    set(ENV{PKG_CONFIG_PATH} ${LIBMESH_DIR}/lib/pkgconfig)
endif ()

I really don't know if there is a convention to check for lib/lib32/lib64 so it works on every system.

I modified the CMakeLists.txt on my computer, I did cmake .. and make and it works if I put /lib instead of /lib64, so it isn't a problem

But if you commit you changes that gets overwritten for everyone else and then it doesn't work for me/simon.

even if I use

libMesh

if (LIBMESH_DIR)
set(ENV{PKG_CONFIG_PATH} ${LIBMESH_DIR}/lib/pkgconfig)
endif ()
in my file too?
(it works with that on my computer)

[jandrej]

oh ok i thought you need to modify the CMakeLists.txt so it finds the path on your OpenSuse system.

it works with both XD after the delete of the previous file yesterday it works with everything we tried before (I don't know why but it's fine 😄 )
