Subject: [PATCH] doc/examples/Makefile.am: define C and C++ compilers for
CMake
This prevents build failures when cross-compiling.
If we don't define the compiler, it will use the one from the host
machine. For instance "/usr/bin/c++", which is incorrect.
The failure looks like this:
.............................................................
