OS: Slackware64-current
lightspark: ff8878a

Boost was updated to 1.70.0 and now lightspark no longer builds with 0.8.1. I next tried the master and it doesn't even get past the cmake configure.

  Found package configuration file:

    /usr/lib64/cmake/boost_filesystem-1.70.0/boost_filesystem-config.cmake

  but it set boost_filesystem_FOUND to FALSE so package "boost_filesystem" is
  considered to be NOT FOUND.  Reason given by package:

  No suitable build variant has been found.

  The included script

This is a cmake / boost issue and can be worked around with -DBoost_NO_BOOST_CMAKE=ON.

Here is a relevant cmake issue report.
