Hm, I noticed that if I do this:
set(my_definitions "UNIX;USE_ITK;USE_FLOAT_PIXELS;")
message("my definitions: " ${my_definitions})
the output is:
UNIXUSE_ITKUSE_FLOAT_PIXELS
but If I put spaces after the semicolons:
set(my_definitions "UNIX; USE_ITK; USE_FLOAT_PIXELS;")
the output is:
UNIX USE_ITK USE_FLOAT_PIXELS
In neither case are the semicolons preserved, which seems bad because
the set_target_properties call expects a semicolon separated list of
preprocessor definitions. Why are these semicolons being removed? They
are in a string (" "), right?
