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:
