When the toolchain involved in openscap build does not support C++, the
configure step fails with the following error:
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - failed
-- Check for working CXX compiler: /bin/false
-- Check for working CXX compiler: /bin/false - broken
CMake Error at /usr/share/cmake/Modules/CMakeTestCXXCompiler.cmake:73 (message):
The C++ compiler
"/bin/false"
is not able to compile a simple test program.
It fails with the following output:

Make openscap depend on proper C++ support.

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

Good point, thanks. I'll send this fix to the upstream project. As
the package is now integrated in master (and so triggering failures
every day in the autobuilder), I guess it is ok to follow-up with a v2
bringing the corresponding patch submitted on the upstream project, even
if not merged yet ?

It is absolutely OK, and is exactly what we would expect :-)
Thanks!
