-Subject: [PATCH] Don't require a C++ compiler
-
-By default, CMake assumes that the project is using both C and C++.  By
-explicitly passing 'C' as argument of the project() macro, we tell CMake
-that only C is used, which prevents CMake from erroring out if a C++
-compiler doesn't exist.
-
-Upstream status: https://github.com/mossmann/hackrf/pull/469
-
-This patch differs from upstream because:
-- project name upstream has been changed into HackRF;
-- in Buildroot, we are only interested in host, not firmware.
