<div dir="ltr">Bonjour Marc,<br />
<br />
Thanks for the reply! Now I get:<br />
(add_custom_command):<br />
Error evaluating generator expression:<br />
<br />
$<SEMILOCON><br />
<br />
Expression did not evaluate to a known generator expression<br />
<br />
I am really just trying to join the INTERFACE_INCLUDE_DIRECTORIES of my target with the "- I" compiler include flags... I have since noticed that I don't get a list indeed, and that:<br />
set(DICTIONARY_INCLUDES " -I$<JOIN:$<TARGET_PROPERTY:MyLibrary,INTERFACE_INCLUDE_DIRECTORIES>, -I>")<br />
does the exact same thing, i.e. the Make/Ninja command is almost perfect if it were not for those backslashes coming out of nowhere at the end of each include path!</div>

<div dir="auto">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:$<TARGET_PROPERTY:MyLIBRARY,INTERFACE_INCLUDE_DIRECTORIES>,<font color="#FF0000">$<SEMICOLON></font>-I>")</div>

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?<br />
