Docker image issue finding header files - c++

Question

I am new to Docker. I am creating a Dockerfile to build my C/C++ application using a custom Makefile. The Makefile builds my code correctly outside Docker and all is good. However, there is an issue when using Docker. My Dockerfile looks as follows :
FROM gcc:latest
RUN apt-get update
RUN apt-get install libboost1.62-*
RUN apt-get install -y libmodbus-dev
COPY . /usr/src/client
WORKDIR /usr/src/client
RUN make -f MyMakefile.mak
CMD [ "bin/runfile" ]
Obviously my code needs libboost and libmodbus and therefore install them first. This was actually all working fine last week, but not now somehow. There is an issue finding the header files for the boost library afterwards though during compilation :

The command '/bin/sh -c make -f MyMakefile.mak' returned a non-zero code: 2
Where would Docker attempt to find these required header files? I would think that in the standard header locations?
