PyIlmBase Cmake unable to find Boost

[bfloch]

We're on linux here and for us all are boost packages are lowercase (without us manually overriding it).

Whatever we do with the current CMakeLists.txt of PyIlmBase FindBoost can not find libboost_python.
-DBoost_DEBUG=ON reveals that it does find the inlcudes, library paths etc. but fails finding the specific component.

Before submitting a pull request I wonder if there is a reason for the current spelling (windows?)

This fixes it for us:

This has been resolved in the new cmake refactor, do note that the next release we will require cmake 3.12 to get the new FindPython goodness. Thanks!
