About Autocmake
|
|
===============
|
|
|
|
CMake typically generates Makefiles based on CMakeLists.txt files. Autocmake
|
|
generates and assembles CMake files based on lightweight cfg-files.

CMake cons
|
|
----------
|
|
|
|
- Complexity
|
|
- Yet another thing to learn: requires learning and training
|
|
- Typically many files instead of one file
|
|
- Documentation ("Which file do I need to edit to achieve X?")
|

CMake pros
|
|
----------
|
|
|
|
- Makes it possible and relatively easy to download, configure, build, install, and link external modules
|
|
- Cross-platform system- and library-discovery
|
|
- CTest uses a Makefile (possible to run tests with -jN)
|
|

Motivation to create a CMake framework library
|
|
----------------------------------------------
|
|
|
|
- Simplify CMake code transfer (scientific projects typically have very similar requirements)
|
|
- FC, CC, CXX
|
|
- Compiler flags
|
|
- Front-end script (setup.py)
|
|
- MPI, OMP, CUDA
|
|
- Math libraries
|
|
- Make it easy for people who know CMake well to create well defined configurations
|
|
- Make it easy for people who do not know CMake to get started in minutes
|
|
- Philosophy
|
|
- Explicit is better than implicit
|
|
- Convention over configuration
|
|
- Well documented set of plug-ins
