Building on MacOS


It turns out in order to build Seer for MacOS, you need to set the cmake qt5 environment variable manually.
You might want to make a note of it in the build instructions with an example:

    In order for find_package to be successful, Qt 5 must be found below the CMAKE_PREFIX_PATH,
    or the Qt5_DIR must be set in the CMake cache to the location of the Qt5Config.cmake file.
    The easiest way to use CMake is to set the CMAKE_PREFIX_PATH environment variable to the install
    prefix of Qt 5.

    I successfully built my GUI on MacOSX 10.10 by exporting Linux environment variables

        $ brew install qt5
        $ ls /usr/local/opt/qt5/lib/cmake/Qt5Widgets/Qt5WidgetsConfig.cmake
        $ /usr/local/opt/qt5/lib/cmake/Qt5Widgets/Qt5WidgetsConfig.cmake
        $ export CMAKE_PREFIX_PATH=/usr/local/opt/qt5/
        $ cd ./build
        $ cmake ../CMakeLists.txt
        $ make -j8


So for Seer on MacOS:

    % cmake -DCMAKE_PREFIX_PATH=/usr/local/opt/qt5/ ..
