Compilation readjustment

[ferxxp]

Solved a compiling error due to templates and added a Dockerfile for future-proofing compilations.

I have updated the DockerFile to the correct repository. I have done all changes to isinf and isnan with a successfull compilation. I have also added at /examples/test_fm.cpp the library due to the error I commented before. I have laso cleansed the commits name just in case. If there is any other suggestion just let me know

Also saludos de la UC3M y de Luis Moreno.

Yes, the compilation for the dockerfile works fine:

docker build . -t fm

Use 'docker scan' to run Snyk tests against images to find vulnerabilities and learn how to fix them

And when used with run and no command we get:

docker run -it --rm fm

I am looking at the best way to add data for custom test ( trying out -v flag so we can find the data in the image). Also working on the explanation fo the read.me that will depend on last decision.

I also was trying a multi-stage file, as suggested, in another branch. However, I'm finding some difficults since some boost .SO are not added to the build directory:

/fast_methods/build/fm_benchmark: error while loading shared libraries: libboost_filesystem.so.1.74.0: cannot open shared object file: No such file or directory

My understanding is that some shared objects are not beeing coppied due to cmake configuration. I am looking into it, but if you have any suggestion or solution I would also try to add that possibility.

I will focuse first on completing the read.me to merge and if i found a solution to that problem, I will add the changes.

Ok, I am afraid I can't help much with the docker stuff. While you figure it out, perhaps it is a good idea to split this PR into 2, one for the compilation issue and another one for the Docker. I would be happy to merge the fix already.

[ferxxp]

Ok, I will work on the Docker when I get some free time. For the moment lets just merge the fix as suggested.

Thank you very much for fixing the compilation issues and helping maintaining the library in a good state.
