Hi Sean, GNU Radio is not handling "X" or anything else in names with special care. (Yes, there's a few blocks that exist as source code templates that we run python scripts over in the build process to actually generate the _c, _f, _b and so on, but this is really not the case here).
This looks much more like a linking error – did you add "FILTER" to the list of "GR_REQUIRED_COMPONENTS" in the main CMakeLists.txt of your OOT? Note that "howto" sounds a bit like our slightly outdated introduction to writing OOT blocks – things should work, but I personally prefer the newer, better-maintained http://tutorials.gnuradio.org .
