+Subject: [PATCH] CMakeLists.txt: fix build without C++
+
+Specify that AvroC is a C project and remove tests_cpp.cpp to avoid the
+following build failure if a C++ compiler is not found:
+
+CMake Error at CMakeLists.txt:20 (project):
+  The CMAKE_CXX_COMPILER:
+
+    /home/naourr/work/instance-2/output-1/host/bin/microblazeel-buildroot-linux-uclibc-g++
+
+  is not a full path to an existing compiler tool.
+
+  Tell CMake where to find the compiler by setting either the environment
+  variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
+  to the compiler, or to the compiler name if it is in the PATH.
+
