Conversation
Forcing an override of `CMAKE_INSTALL_PREFIX` is not friendly, since users might expect to set it themselves when they run cmake.

CMAKE_INSTALL_PREFIXis not friendly, since users might expect to set it themselves when they run cmake.We have a real-world use case where we do set this ourselves when running cmake. We build the libraries on each platform separately, setting
CMAKE_INSTALL_PREFIXto a nice place outside of the source. Only afterwards do we combine all of the results from each platform and put them in the final location.
