Issue body

Got an g++ file not found error, whilst using the catkin_plugin for snapcraft, Here is the error: -- Build files have been written to: /home/mil607/snap/parts/workspace/build/build_isolated/nabo ==> make -j8 -l8 in '/home/mil607/snap/parts/workspace/build/build_isolated/nabo' Scanning dependencies of target nabo [ 5%] Building CXX object CMakeFiles/nabo.dir/libnabo/nabo/nabo.cpp.o [ 10%] Building CXX object CMakeFiles/nabo.dir/libnabo/nabo/brute_force_cpu.cpp.o [ 15%] Building CXX object CMakeFiles/nabo.dir/libnabo/nabo/kdtree_cpu.cpp.o g++: fatal error: no input files compilation terminated. g++: fatal error: no input files compilation terminated. /bin/sh: 1: -fopenmp: not found CMakeFiles/nabo.dir/build.make:86: recipe for target 'CMakeFiles/nabo.dir/libnabo/nabo/brute_force_cpu.cpp.o' failed make[2]: *** [CMakeFiles/nabo.dir/libnabo/nabo/brute_force_cpu.cpp.o] Error 127 /bin/sh: 1: -fopenmp: not found make[2]: *** Waiting for unfinished jobs....

The original flags.make with the error is here, the error is in line 5 near the end, before the -fopenmp flag: 1 # CMAKE generated file: DO NOT EDIT! 2 # Generated by "Unix Makefiles" Generator, CMake Version 3.5 3 4 # compile CXX with /home/mil607/snap/parts/workspace/compilers/install/usr/bin/g++ 5 CXX_FLAGS = -I/home/mil607/snap/parts/workspace/install/usr/include -I/home/mil607/snap/parts/workspace/install/usr/includ e/x86_64-linux-gnu -I/home/mil607/snap/parts/workspace/compilers/install/usr/include -I/home/mil607/snap/parts/workspace/co mpilers/install/usr/include/x86_64-linux-gnu/c++/5.4.0 -I/home/mil607/snap/parts/workspace/compilers/install/usr/include/c+ +/5.4.0 -I/home/mil607/snap/parts/workspace/compilers/install/usr/include/x86_64-linux-gnu;-fopenmp -O3 -DNDEBUG -fPIC 6 7 CXX_DEFINES = -DEIGEN_DONT_ALIGN -DEIGEN_DONT_ALIGN_STATICALLY -Dnabo_EXPORTS 8 9 CXX_INCLUDES = -I/usr/include/eigen3 -I/home/mil607/snap/parts/workspace/install/usr/include -I/home/mil607/hovermap/src/ct -slam/src/nabo/libnabo/nabo Not sure if the catkin plugin has generated it or is due to some other file that might have had an inadvertant semi-colon included. But its a possible bug. I'm still investigating and will provide any updates.
