Installing OpenPFC does not install everything

[ahojukka5]

Installing OpenPFC (cmake --install build) does not install the examples and apps to the installation directory (CMAKE_INSTALL_PREFIX), but they are in the build directory (in the source tree).

Upon further consideration, it seems that this may be desired. We only need to install the header files and libraries without any examples or apps. While we could potentially install documentation and examples for sharing purposes, it's also acceptable not to install them. Currently, we are installing the following:

We also have issue #41, and if we have some more general binaries, they might go to /bin. For now, I don't make any changes to this.
