+Subject: [PATCH] Revert "Enable CXX language to support using
+ GenerateExportHeader"
+
+This reverts commit 23d68e8c798d29309a277fb3c869c23f9cac2bbf. Indeed,
+GenerateExportHeader has been removed with commit
+db5a2c216b122c57dc281aea2f3b7afa210dc0fc and ENABLE_LANGUAGE(CXX) will
+raise the following build failure if no C++ compiler is found:
+
+CMake Error at CMakeLists.txt:34 (ENABLE_LANGUAGE):
+  The CMAKE_CXX_COMPILER:
+
+    /home/buildroot/autobuild/instance-1/output-1/host/bin/arm-linux-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.
+
+Fixes:
