Eclipse CDT: Disabled build settings (Windows)

If you using Eclipse CDT under Windows OS, you can have some troubles when creating project and trying to change build settings, such as builder, build dir and other. It's happen when you choose toolchain for project.

Using toolchains is good, because eclipse automatically imports include dirs and macros for choosed compiler and add it to indexer. On screenshot above you can see default settings for mingw compiler.

But, if you using toolchain all settings on build settings page looked grayed, so they are disabled.

If you want to allow Eclipse change builder settings you need to open C++ Build - Tool Chain Editor tab and select another builder. See screenshot above.

You can choose Gnu make builder or linuxtools builder, i didn't see difference. 

Now, you can customize builder settings.
