Following the instructions, fails to compile. "Missing GnuradioConfig.cmake, gnuradio-config.cmake"

[JohnCC330]

Executing the compilation recipe:

mkdir build
cd build
cmake ..
make
sudo make install
sudo ldconfig

Fails at the cmake .. step:

CMake Error at CMakeLists.txt:77 (find_package):
  By not providing "FindGnuradio.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Gnuradio",
  but CMake did not find one.

I'm not familiar with the cmake process...
