Patches "qt4-fail-silent.patch" and "support-oe-qt4-tools-names.patch"
were adapted in order to fit to CMake 3.2.2 (refer to the commit
message in the respective patch for details).
Patch "cmake-2.8.11.2-FindFreetype.patch" was dropped since it was
rejected upstream and its functionality otherwise implemented in the
meantime.

Note that CMake 3 needs to have the full compiler path in the toolchain
file (see cmake.bbclass).
Why is the full path needed?

Have you try to add STAGING_BINDIR_TOOLCHAIN to the CMAKE_FIND_ROOT_PATH?

Why you don't use the full path for AR?
