Travis build can't find boost libs

[ryanlevy]

As discovered in #47, Travis fails on the cmake scripts when finding boost_program_options (the compiled lib)

It might be an ALPSCore problem, i'll look at it shortly.

I've loaded up a Ubuntu 14.04 VM and cannot replicate this error for some reason

Thanks!

[ryanlevy]

Correction: this happens in my Ubuntu 18.04.1 LTS

[galexv]

What is the cmake version in Ubuntu 18.04?

[ryanlevy]

version 3.10.2 (and 3.5.1 in 14.04 which seems to be behind travis)

[galexv]

Thanks!
In the Travis build CMake 3.9.2 is used.

[galexv]

...and i can reproduce the error with CMake 3.9.6.

[galexv]

Quick workaround: in CMakeLists.txt, right after find_package(ALPSCore 2.0 REQUIRED), add set(Boost_NO_SYSTEM_PATHS false).

[ryanlevy]

That fixes it with cmake 3.10.2!

It's a bug in ALPSCore, i am thinking how best to fix it while still deterring the ALPSCore user from accidentally finding the wrong Boost.
So, do not add this workaround to the repository yet: it's better to have ALPSCore fixed.
