LD_LIBRARY_PATH is irrelevant at build time.  It is an alternative to
setting RPATH in the build (-Wl,-rpath,/path/to/opencascade/lib with a
gcc-style toolchain), but not an alternative to a library path
(-L/path/to/opencascade/lib).  LIBRARY_PATH is formally an alternative
to -L, but it is almost never used.  Depending on environment variables
to locate libraries is fragile as hell, and totally non-standard for
autotools builds.

Pass -L/path/to/opencascade/lib.
