Looks like I need to set the path to mpir for the make file it seems.

nvcc -g -O2 -I . -Xptxas "-abi=no -v" -gencode=arch=compute_30,code=\"sm_30,compute_30\" -gencode=arch=compute_35,code=\"sm_35,compute_35\" -gencode=arch=compute_50,code=\"sm_50,compute_50\" --maxrregcount=80 --ptxas-options=-v -I./compat/jansson -o x13/m7.o -c x13/m7.cu
