Is there an equivalent command to link_directories that support

link_directories(
$<$<CONFIG:Debug>:${PROG_LIBRARY_DIRS_RELWITHDEBCRT}> )
link_directories( $<NOT:$<CONFIG:Debug>>:${PROG_LIBRARY_DIRS}> )
Basically I want to use PROG_LIBRARY_DIRS_RELWITHDEBCRT for Debug
builds and PROG_LIBRARY_DIRS for everything else.
I'm sure I can go and use set_target_properties or something like
that, but I was wondering if there was some way I could make this
work, before I have to do a much larger change.
The documentation for link_directories() notes that the command is
rarely necessary since target_link_libraries() takes absolute paths.
target_link_libraries() itself understands generator expressions.
What is your use case for link_directories()?
If absolutely need be a viable though I guess not portable and possibly
frowned upon workaround might be something like:
target_link_libraries(foo PRIVATE -Lfoo/$<CONFIG>/bar) # assumes -L
adds a linker directory
Given that target_link_libraries() also allows (non library) linker options.
