OSX and "is not a valid Mach-O binary"

[ravas]

Using Qt 5.5.1 / creator, OSX 10.11.3 and clang I get dialogs that popup after the build (during start up of the program) that say:

'/Users/one/Documents/LibreCAD/plugins/Makefile' is not a valid Mach-O binary (invalid magic 23232323)
'/Users/one/Documents/LibreCAD/plugins/plugins.pro' is not a valid Mach-O binary (invalid magic 232d2d2d)
'/Users/one/Documents/LibreCAD/plugins/plugins.sln' is not a valid Mach-O binary (invalid magic 4d696372)
'/Users/one/Documents/LibreCAD/plugins/README.plugins' is not a valid Mach-O binary (invalid magic 46697273)

Any idea why this would be happening? The program successfully loads after dismissing these dialogs.
