Revert "Enable CXX language to support using GenerateExportHeader" 

This reverts commit 23d68e8c79. Indeed,
GenerateExportHeader has been removed with commit
db5a2c216b 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:
