many projects now have multiple build systems. Different build system to solve the exact same problem and can exist together.

Build system CMake is very popular and very flexible. It has good support in various IDE.

Using popular build system may increase the popularity of your projects.

Example for autotools:

./autogen.sh
./configure
make
make install

Example for CMake:

cmake .
make
make install

You can see that after the configuration stage, both systems work identically.

Adrian, from your answer, I do not understand, can I expect that you will merge my changes?

In the future I plan to add a CMake build system in the project Ragel, too.
