[CMake] unexpected INSTALL problems

Problem is boost has very complicated linking scenario. Using
FindBoost and linking to it hardcodes the versions, because they are
in the filenames! If I need to run on another system I must have
exactly the same boost version, but that is almost never the case.

The problem here is that FILE() only runs at configure time, while
INSTALL on building the install target. We can not accept that on
other reasons, we need to have the full installation in one go.

So I conclude it is not possible.

Many thanks for your response.
