Unable to build surround360_render

[rinka-meltiron]

Background
I am running this on Kubuntu 16.04.04 LTS, a fresh install.
The error I get while linking surround360_render is:

Using instructions at: https://github.com/facebook/Surround360/tree/master/surround360_render

• I followed the instructions except for the ones for the python, numpy, pip. gooey, pil installs (I don't need python).
• Installed ceres as described here, not on the ceres git page.
• installed llvm, Halide to use accelerated ISP

and I get the error above while make'ing ...360_render

What I've tried so far

• Folly Gooey problem: Folly and Gooey problem #253 Failed. I get:

• assuming it is a problem with the standard double-conversion-dev library installed by apt, I uninstalled that, recompiled double-conversion:

    git clone https://github.com/google/double-conversion.git
    cd double-conversion
    cmake -DBUILD_SHARED_LIBS=ON .
    make -j $(nproc)
    sudo make install

• and rebuilt folly as follows:

    $ cmake configure ..

didn't work. redid cmake & make

    $ cmake configure "-DCMAKE_INCLUDE_PATH=$HOME/bin/fb-lib/double-conversion/build/include" "-DCMAKE_LIBRARY_PATH=$HOME/bin/fb-lib/double-conversion/build//lib" ..

error:

CMake Error at CMakeLists.txt:201 (find_package):
  Could not find a package configuration file provided by "double-conversion"
  with any of the following names:

    double-conversionConfig.cmake
    double-conversion-config.cmake

  Add the installation prefix of "double-conversion" to CMAKE_PREFIX_PATH or
  set "double-conversion_DIR" to a directory containing one of the above
  files.  If "double-conversion" provides a separate development package or
  SDK, be sure it has been installed.

:-(

OK. I've fixed it. It required a change to CMakeLists.txt. I've tested it for Ubuntu 16.04 (both Release and Debug) but couldn't test for APPLE and MSVC as I don't have those environments.
Below is the patch to be applied to CMakeLists.txt

Please feel free to copy, test and use. Thanks.
