He compilado caffe con GPU desactivada, luego

cp caffe/build/Makefile openpose/Makefile.conf

correr

 make all -j 6

tengo estos errores:

no puedo encontrar opencv, y compilé el último opencv 3.2-dev de la fuente, todos los programas de opencv (tanto c ++ como python) funcionaron, así que ¿por qué no puedo encontrar find opencv?
