store configuration macros in header #21
Description
In header files there are macros used like PROFILE_OP_COUNTS or BINARY_OUTPUT. They are defined in CMakeLists.txt and used for building library. But they aren't stored anywhere, so the user of library by default has them undefined.
CMake has direct support for generating such headers: https://cmake.org/cmake/help/v3.13/command/configure_file.html
