Exception: secp256k1_schnorr not enabled

[pereferrera]

Hi there,
I can't find much information on how to compile libsecp256k1 for Schnorr support, I simply tried to clone the latest version of the lib and compile it and still got the same error. Any ideas?

#NOTE: default prefix[/usr/local/]
$./configure --enable-experimental --enable-endomorphism --enable-module-schnorr --enable-module-recovery 
$make
$sudo make install

#reinstall secp256k1
$pip uninstall secp256k1 cffi
$env SECP_BUNDLED_EXPERIMENTAL=1 INCLUDE_DIR=/usr/local/include LIB_DIR=/usr/local/lib pip install --no-binary :all:  secp256k1 --no-cache-dir
