(cherry picked from commit 1571f176fc37dda1c3e889776e13fa49bba4ae42)
Each time the dependency build was run, previously, the build system
attempted to patch wxWidgets after checking it out from Git. The problem,
of course, is that if this happened once, it would not succeed a second
time, so the only workaround was to blow away the wxWidgets source tree.
The real solution to this is to create a BBL fork of wxWidgets (or to
upstream the changes...). But for now, we add a file to determine whether
the patch has taken place already, and if it's there, we don't apply the
patch again. This will mean that all kinds of exciting things happen if you
change Git revisions of wxWidgets or the patch changes (in those cases,
you'll have to blow away the build), but at least this makes it possible to
build twice in the same repository in the best case.
To update an existing checkout, run:
$ touch deps/build/dep_wxWidgets-prefix/src/dep_wxWidgets/WXWIDGETS_PATCHED
On Linux, wxGTK by default attempts to use EGL if it is available on the
system, rather than GLX. Unfortunately, the ancient version of GLEW that we
packaged in did not support EGL, and even if it did, the configuration was
not set up to enable EGL. To solve this, we:
* upgrade GLEW to version 2.2.0, from upstream GitHub
* modify the Bambu build process to enforce that we use GLEW from the
built dependency
* remove the "extra" even older GLEW that was packaged
* modify GLEW's CMake configuration to enable EGL support when it is
available on the system (using the same test as wxWidgets uses to decide
whether to enable EGL support); if EGL isn't available at compile time,
both GLEW and wxWidgets will fall back on GLX
Note that you probably will have to blow away your CMakeCache for this to
work correctly -- otherwise, you may end up with the system GLEW, if you
have one installed (which is probably not what you want -- on Ubuntu, the
system GLEW is GLX, not EGL).
