Builds fine on debian unstable with 2.18.18 for me:

apt-get install libfann-dev libpoco-dev libqwt5-qt4-dev libeigen3-dev
svn checkout http://svn.code.sf.net/p/qrap/code/ qrap
mkdir qrap/build/
cd qrap/build/
# apply attached minor patch
cmake -D CMAKE_MODULE_PATH=/usr/share/qgis cmake -D POSTGRES_LIBRARY=/usr/lib/x86_64-linux-gnu/libpq.so -D PQXX_LIBRARY=/usr/lib/x86_64-linux-gnu/libpqxx.so  ..
make && sudo make install
