[vlc-devel] [PATCH] contrib: Set _CMAKE_TOOLCHAIN_PREFIX

[Martin Storsjö]

This is required for detecting ar and ranlib properly, required
e.g. when cross compiling for android from OS X.

One can't set CMAKE_AR or CMAKE_RANLIB directly. Normally they
should be set properly automatically within cmake, but those
codepaths seem to be skipped when we set the C/CXX compilers
manually.

---
Would it make sense to do this for all cases, not only for
android? (The condition basically is "whenever $(HOST) is set
properly".)
