This reverts commit 4b01201834.
Before reverting this patch, CMake packages are built with the following
options:
* if BR2_ENABLE_DEBUG is set:
The CMake build type is set to RelWithDebInfo, which means:
- Optimization level is forced to: -O2;
- no log nor assert due to -DNDEBUG;
- BR2_DEBUG_{1..3} effect is unchanged;
* otherwise:
The CMake build type is set to Release, which means:
- Optimization level is forced to: -O3;
- no log nor assert due to -DNDEBUG (as expected).
In any case, the optimization WRT the binary size is always ignored
and forced.
Reverting to the previous situation, so Buildroot now chooses between
the 'Debug' and 'Release' config types, which are semantically closer
to what Buildroot does everywhere else:
* if BR2_ENABLE_DEBUG is set:
The CMake build type is set to Debug, which means:
- only -g option is passed by CMake;
- optimization is not forced, nor debug level, so they are kept
as-is;
* otherwise:
The CMake build type is set to Release, so no change in this case:
- Optimization level is forced to: -O3;
- no log nor assert due to -DNDEBUG (as expected);
- size optimization is ignored.
Follow-up patches will fix the CMake flag variables that are appended by
CMake.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
