Hello Alexis,

Thanks for the fix!

From a quick look, it doesn't seem like openscap contains C++ code. So
instead the right fix is most likely to change CMakeLists.txt to check
for the C compiler only.

To do that, in CMakeLists.txt, change:

project(blabla)

to

project(blabla C)

Best regards,

Thomas
