[CMake] Autogenerating CMakeLists.txt

[Marcus]

Hi,

Please could I ask for your opinions on automatically generating 
CMakeList.txt files, rather than editing them directly.

My motivation is that I am working on several projects, each broken-down 
into sub-projects, and all of them use a consistent directory structure. 
  I want to take advantage of this uniform structure to minimise the 
maintenance work involved in editing CMakeLists.txt files.

By assuming a uniform directory structure, and adding a small 
meta-information file to each project, I believe the CMakeList.txt files 
could be automatically generated.  The meta-information would only include:

* project name
* names of dependencies
* list of sub-projects

The generator would glob for files within each project, so it would be 
necessary to rebuild the CMakeList.txt files if meta-information is 
changed, or if new files are added to a project.  Ideally, the generated 
build system should issue a warning when the CMakeLists.txt files are 
out of date.

Please let me know if you think this is a feasible (and sensible) solution.

Many thanks,
Marcus
