The Buildroot package explicitly avoided that by forcing CMAKE_BUILD_TYPE to 'RelWithDebInfo' when pkg-cmake.mk would normally set it to 'Debug'. Until recently, this was the case when BR2_ENABLE_DEBUG was enabled. A previous commit changed the condition under which CMAKE_BUILD_TYPE=Debug was set, from BR2_ENABLE_DEBUG=y to BR2_ENABLE_RUNTIME_DEBUG=y, so logically the flare-engine package would have to be updated accordingly. However, apart from the profiling flag, the flare-engine package only uses CMAKE_BUILD_TYPE to determine flags that Buildroot wants to control itself, like optimization and debugging flags. This means we can fake CMAKE_BUILD_TYPE to a value that has no meaning for flare-engine itself, without needing to check BR2_ENABLE_DEBUG nor BR2_ENABLE_RUNTIME_DEBUG. Incidentally, this trick was already done in case BR2_TOOLCHAIN_HAS_GCC_BUG_85180 was true, so move that line out of this condition. Signed-off-by: Thomas De Schampheleire Signed-off-by: Yann E.
