LD_LIBRARY_PATH is for the dynamic linker when you start something. CMake
doesn't look at this. It will look into e.g. /usr/lib and /usr/lib64
(depending on your system), but not into /usr/lib/x86_64-linux-gnu. You
can tell it to try by setting CMAKE_PREFIX_PATH=/usr/lib/x86_64-linux-gnu
before calling CMake.

I have no idea about autoconf, that's why I use CMake ;)
