[Bug 2007178] Re: Replace GLEW with epoxy

 

First I need to check how to build on Windows. The readme does not
provide instructions specific for Windows. It seems epoxy needs 2!
different build systems (currently not used by Hugin or its
dependencies) which would be a high obstacle for building such a small
library.

Second this lib is new for me and I don't know how enduring it is or how
good the maintenance is. Last year there were only 5 commits to the
repo.

A further point is that the patch is very invasive. It changes many
files where GLEW is not used at all. Is this really necessary?

Title:
  Replace GLEW with epoxy

Status in Hugin:
  New

Bug description:
  GLEW is installed for either GLX or EGL, making it impossible to switch to EGL if some applications need GLX.
  epoxy also does not need to be initialised, making startup faster.
  GTK, Firefox and Libreoffice are among those using epoxy.

  Patch (not sure the best way to work with Launchpad and/or Sourceforge...):
  https://sourceforge.net/p/hugin/hugin/merge-requests/2/

  A draft that has only been tested on Linux and at the moment uses
  PKG_SEARCH_MODULE to find epoxy. So, may work on macOS (libepoxy is
  available in Homebrew) but more work for Windows and other supporting
  scripts.
