Add eigen3 support

mentioned in merge request !315 (closed)

changed the description

@fomenko what distribution are you using?

I suggest in the meantime you:

Install MPDroot according to the new instructions
Install Eigen3 package for your distro from the package
Adapt the files you are developing for AlignKalman, so they will use the eigen3 library from this package

Eigen3 support will be soon in mpdroot and you will push only the files you are actively developing.

Thank you for your support.

1.Install MPDroot according to the new instructions

I use apr21 branch of fairsoft/root and dev branch of mpdroot + my sources

2.Install Eigen3 package for your distro from the package

Already installed

3.Adapt the files you are developing for AlignKalman, so they will use the eigen3 library from this package

I've just added appropriate include path to tpc/CMakeLists.txt as a temporary workaround

My suggestion was that you will in the meantime adapt your mpdroot codebase so it won't include eigen3 sources. (Example: we use fftw3 package and it is not included in our codebase) It will be easier for you later to push your changes, when eigen3 support will be added. But nevermind we can wait: once eigen3 support is added, we can add your changes once they pass all tests.

Already implemented on new build system nicadist#6 (closed) ..

My guess is in next few days, it will be supported also for old installation procedure. @fomenko you can then install it, and push your changes without eigen3 library files.

Great! Thank you for information.
