[CMake] Separating spaces are escaped by JOIN generator expression

[Marc CHEVRIER]

If you want to define a list, try to use $<SEMICOLON> rather than a space to separate the items. This way, you will get a CMake list rather than a string: list(APPEND DICTIONARY_INCLUDES "-I$<JOIN:$<TARGET_PROPERTY:MyLIBRARY,INTERFACE_INCLUDE_DIRECTORIES>,$<SEMICOLON>-I>")

> I am facing the exact same issue when when joining libraries from a target for some CMake function defined by the Cern ROOT library (ROOT_GENERATE_DICTIONARY in that case). I am defining a list: list(APPEND DICTIONARY_INCLUDES " -I$<JOIN:$<TARGET_PROPERTY:MyLIBRARY,INTERFACE_INCLUDE_DIRECTORIES>, -I>") which is then passed to the ROOT function. I can see from the build error that all the includes have a backslash appended, i.e.: ... -I/home/user/lib1/include/\ -I/home/user/lib2/include/\ -I... The BUILD_INTERFACE vs INSTALL_INTERFACE is respected, everything seems to work aside from these nasty backlashes... If I save the command manually after seeing the error and perform a string replacement to remove the backlashes, I get the desired result. Is there any fix five years later?
