Chose an install directory that makes sense
for you. /opt works well since it has the correct
permissions.

cd gnuradio
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/opt/gnuradio ..
make
sudo make install

This will build GnuRadio and install it in /opt/gnuradio

Will this later cause problem with OOT created with earlier version of gr_modtool?

It seems that the "/usr/local" has been "hard-coded" into some files of the OOT, as shown below.

Hence the OOT installation may fail to put all necessary files correctly into "/opt/gnuradio".

    address@hidden: ~/gnuradio/gr-mymodule1 $ grep -R /usr/local
    cmake/Modules/FindGnuradioRuntime.cmake:    PATHS /usr/local/include
    cmake/Modules/FindGnuradioRuntime.cmake:    PATHS /usr/local/lib

Custom install locations do require some additional environment
setup. Sylvain gave me a nice shell script for that.

BASE=/opt/gnuradio
export PATH=${PATH}:${BASE}/bin
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${BASE}/lib64
export PKG_CONFIG_PATH=${PKG_CONFIG_PATH}:${BASE}/lib64/pkgconfig
export PYTHONPATH=${PYTHONPATH}:${BASE}/lib64/python2.7/site-packages/

Just change the first line to the directory of  your custom install.
Setting PKG_CONFIG_PATH will resolve finding packages
in OOT builds. Remember to use the same custom install prefix
in the cmake of your OOT builds.
