It will be in $BUILD_DIR/install

We don't use it anymore.

Start working on custom code-style/code-requirements file checker.
So far we check only for missing license, for non-standard EOL (\r) and
for files that not-compliant with clang-format.

Remove CMakeLists.txt generator scripts from build phase. Replaced with
CMake's GLOB that can re-run every time the build is invoked. We can
also drop the Python dependency now.

Removed header installs which will be redesigned in future commits.
