I think PATH is for executables and not libraries.
maybe looking into what LD_LIBRARY_PATH does or the output of
ldconfig -p | grep clang
Also look at the files /etc/ld.so.conf /etc/ld.so.conf.d/*
I've seen cmake or configure scripts having there own way of finding
libraries to link to. I have had to do something like this a couple of
times.
export LIBPNG_CFLAGS="-I/usr/include/libpng16"
export LIBPNG_LDFLAGS="-L/usr/lib -lpng16"
I hope this gives you a little idea of what to search for.
