Line 1451 of configure.in sets up the SpatialIndex configuration as follows:
CC="${CC}" CXX="${CXX}" CFLAGS="${env_cflags}" CXXFLAGS="${env_cxxflags}" CPPFLAGS="-D_GNU_SOURCE" \
LIBS="${env_lib}" ./configure --prefix=${PWD}/../ --disable-shared --without-pic \
${SPATIALINDEX_CONFIGURE_DEBUG_OPTION} ${SPATIALINDEX_CONFIGURE_PROF_OPTION} --disable-maintainer-mode
There is no env_lib variable. Line 52 sets env_libs which is probably the intention. The current setup just sets LIBS to the empty string which is probably perfectly fine as well.
