#359 BASIS_EXPORT_TARGETS is now an advanced user option that defaults to OFF. This improves performance noticeably, and avoids bugs in the export targets when external/imported shared libraries from other modules or projects are used.
Revert "#359 BASIS_EXPORT_TARGETS is now an advanced user option that defaults to OFF. This improves performance noticeably, and avoids bugs in the export targets when external/imported shared libraries from other modules or projects are used."

This reverts commit 3b3027ac1a523fe3a410b265183aec638b844ef7.
#359 BASIS_EXPORT is now an option flag, and linked libraries are added to the export list.
#340 Move BASIS_BUILD_ONLY definition to more appropriate location and edit help.
#340 Remove BASIS_SYTEM_CHECKS option. Instead, perform these (required) checks only for the build of BASIS itself.
