+Subject: [PATCH] cmake: allow build without c++
+
+By default cmake also searches for a c++ compiler:
+https://cmake.org/cmake/help/v3.7/command/project.html
+"By default C and CXX are enabled if no language options are given."
+
+This patch restricts the compiler to C to fix a build error detected
+by the buildroot autobuilders:
+http://autobuild.buildroot.net/results/c04/c04ff29b83c020573add597c355c57a6d9c9761d/build-end.log
