You need to append to the list in the dictionary entry, not assign it.

Use setdefault() to provide a default empty list if the dictionary key doesn't exist yet.

Let us do in steps

• Reset the index of df1
• Merge df1 with df2 on column A (basically merge rows with same genes)
• Query the merged dataframe to filter the rows where column D falls between B and C
• Flag the rows by testing the membership of index of df1 in the index column of filtered rows

Generator expressions are usable only for some properties and some variables, so they could be evaluated at the end of configuration stage to a values, which depends from the build type. Such behavior cannot be achieved with plain if because multi-configuration CMake generators (like Visual Studio) read a CMakeLists.txt once but create several configurations.

Generator expressions are usable also for the commands which sets these properties and variables.

Every possible usage of generator expressions is explicitly stated in the documentation for a command/property/variable which supports them.

Documentation for the command set_target_properties doesn't describe usage of generator expressions, so this command simply doesn't support them.

Actually, one can pass to that command a generator expression as a property's value. In that case the command will just assign that value to the corresponded property. It is dependent from the property whether the generator expression will be resolved when evaluate the property after the configuration.

But neither the name of the target not the name of the property cannot be a generator expression.

For conditionally set properties for a target, use plain if:

Try this example:

I checked the code you posted and I see that you are updating the list of objects, in your case listItems, instead of a ListItem in ListItemCollection, in your case listItemCol. To be more clear, I believe you can try to replace listItems with listItemCol. For instance, instead of:
