installation from source

[gszep]

Describe the bug
I performed the following operations on my machine to install IGoR from source

git clone git@github.com:qmarcou/IGoR.git
cd IGoR
./autogen.sh
./configure
make

which fails with the following error

g++ -DHAVE_CONFIG_H -I. -I..    -I./../libs/jemalloc/include/jemalloc -I./../libs/gsl_sub -fopenmp -DIGOR_DATA_DIR=\"/usr/local/share/igor\" -g -O2 -MT igor-ExtractFeatures.o -MD -MP -MF .deps/igor-ExtractFeatures.Tpo -c -o igor-ExtractFeatures.o `test -f 'ExtractFeatures.cpp' || echo './'`ExtractFeatures.cpp
