Build fails if working directory contains special symbols like +

[vjpr]

E.g. If you working dir is: ~/dev/+bun/bun

${CWD} needs to be escaped because it is used as part of a regex.

  foreach(source ${CMD_SOURCES})
    if(NOT source MATCHES "^(${CWD}|${BUILD_PATH}|${CACHE_PATH}|${VENDOR_PATH})")
      message(FATAL_ERROR "register_command: SOURCES contains \"${source}\", if it's a path, make it absolute, otherwise add it to TARGETS instead")
    endif()
    list(APPEND CMD_EFFECTIVE_DEPENDS ${source})
  endforeach()
