CMake

CMake is a cross-platform, open source Makefile generator that is supposed to help managing build processes.

Invoking

Unlike make, cmake usually is not invoked in the same directory as the project (= out of source build). 
$ cmake path/to/project
creates a Makefile in the current directory.
The instructions for the Makefile are found in path/to/project/CMakeLists.txt.

CMakeLists.txt

A CMakeLists.txt can reference CMakeLists.txt in other sub-directories.

Forcing to print the building statements

The Makefile generated by CMake can be forced to print the building commands with make VERBOSE=1.

Bloated

suckless.org writes
cmake (written in C++) - so huge and bloated, compilation takes longer than compiling GCC (!). It’s not even possible to create freestanding Makefiles, since the generated Makefiles call back into the cmake binary itself.
