OPTION A: Put quotes around a semi-colon separated string if using
set_target_properties():
set_target_properties(target PROPERTIES
IMPORTED_LOCATION location
IMPORTED_IMPLIB implib
INTERFACE_INCLUDE_DIRECTORIES "directory1;directory2"
)
OPTION B: List multiple directories after just one INTERFACE keyword if
using target_include_directories():
target_include_directories (target
INTERFACE directory1 directory2
)
Either option should work for all platforms, but note that option A will
overwrite any previous contents of INTERFACE_INCLUDED_DIRECTORIES whereas
option B will append to any previous contents. For that reason, I'd
generally recommend option B.
