how can build gr-osmocomsdr in a linux that gnuradio is built and installed in a custom dir?

[sp]

I installed Gnuradio in /home/sp/disk1/install/usr/local directory when I
want to build gr-osmocomsdr I faced this error...
in bashrc i add some environment variables that Gnurado works  uhd works
but for Gnuradio it can not detect Gnuradio I set all environments correctly
How can solve my problem?
thanks in advance

  Target "gnuradio-osmosdr" links to target "gnuradio::gnuradio-blocks" but
  the target was not found.  Perhaps a find_package() call is missing for an
  IMPORTED target, or an ALIAS target is missing?
