fix(Conan): Fix build from source and creation of packages

Done:

• Use CMake within Conan as much as possible (do not reinvent install logic)

• linux: fix build from source for packages osi, fmi

• linux: openpass can be build with osi and fmi as Conan packages

• windows: fix build from source for packages osi, fmi

• windows: openpass can be build with osi and fmi as Conan packages

Probably need to be fixed in near future:

• check if it is really necessary to build boost and qt from source and deploy as Conan package

• linux: better way to insert c/c++ compiler dependencies into conanfile.py (right now, hardcoded e.g. CMAKE_CXX_COMPILER=g++-10)

• fix build from source for packages boost, qt (interesting for linux only?)

• openpass can be build with osi, fmi, boost and qt as Conan packages (interesting for linux only?)

• fix build with tests enabled

• fix build with gui enabled

General ideas:

• CMake variables as Conan options so that they can be set without touching the conanfile.py
• Right now, openpass thirdparties get copied in the same directory ThirdParty during build process and share common directories like bin and lib (not so clean)
• creation of top-level profiles including settings regarding operation system (win/lin), compiler used(gcc9, gcc10) etc.
