Debug

Compile recipe without striping and with debug info

DEBUG_BUILD = "1"
#
# Uncomment this to disable the stripping of the installed binaries
INHIBIT_PACKAGE_STRIP = "1"
#
# Uncomment this to disable the split of the debug information into -dbg files
INHIBIT_PACKAGE_DEBUG_SPLIT = "1"

Above is enough to enable debug build and symbols. If not it is always possible to add:

EXTRA_OECMAKE += "-DCMAKE_BUILD_TYPE=Debug"
CFLAGS += "-g"
