Compliation issue: Cannot find a library with BLAS API, LAPACK API ?

[errer]

Hello,

On 64-bit Ubuntu machine, I have compiled & install OpenBLAS and LAPACK from source, then did export as such :

export BLAS_LIBRARY_PATH=/opt/OpenBLAS/lib
export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:${BLAS_LIBRARY_PATH}"

cd src

Build overfeat

make all, showing message as follows :

notice these 3 lines particularly :
-- Cannot find a library with BLAS API. Not using BLAS.
-- LAPACK requires BLAS
-- Cannot find a library with LAPACK API. Not using LAPACK.

seems that in the final built bin file overfeatcmd :

libopenblas.so.0 is not linked, couples of libs are missed :

The wrong version :
linux-vdso.so.1 => (0x00007ffea8dce000)
/usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f722f615000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f722f2e3000)
libgomp.so.1 => /usr/lib/x86_64-linux-gnu/libgomp.so.1 (0x00007f722f0d4000)
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f722eebd000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f722ec9f000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f722e8da000)
/lib64/ld-linux-x86-64.so.2 (0x00007f722f91c000)

The correct one should be :
linux-vdso.so.1 => (0x00007ffc0717d000)
/usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f8f1127f000)
libopenblas.so.0 => /opt/OpenBLAS/lib/libopenblas.so.0 (0x00007f8f104da000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f8f101a8000)
libgomp.so.1 => /usr/lib/x86_64-linux-gnu/libgomp.so.1 (0x00007f8f0ff98000)
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f8f0fd82000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f8f0fb64000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f8f0f79e000)
/lib64/ld-linux-x86-64.so.2 (0x00007f8f11586000)
libgfortran.so.3 => /usr/lib/x86_64-linux-gnu/libgfortran.so.3 (0x00007f8f0f485000)
libquadmath.so.0 => /usr/lib/x86_64-linux-gnu/libquadmath.so.0 (0x00007f8f0f248000)
