Archived issue #0028197
Configuration - support Eigen template library as external dependency
Description
In scope of modeling meeting from 2016.12.07 it was decided to add Eigen third party. This library provides set of methods for linear algebra. So, it will be useful for particular cases where performance is important
It is proposed to add CMake flag which defines usage of this library. This flag should be turned off by default.
It is proposed to add CMake flag which defines usage of this library. This flag should be turned off by default.
Steps to reproduce
• Add "CSF_EIGEN" line into some toolkits EXTERLIB file.
• Turn ON CMake variable "USE_EIGEN".
• Set 3RDPARTY_DIR to the location of your third-parties (with Eigen third party)
• Press Configure -> Generate.
• Open generated solution and check that all toolkits contain path to the Eigen header file if toolkit properties (Additional Include Directories).
• Add some code with usage of Eigen third party (include an Eigen header file and use some Eigen class).
• Check usage of HAVE_EIGEN preprocessor definition.
• Compile the solution.
• Turn ON CMake variable "USE_EIGEN".
• Set 3RDPARTY_DIR to the location of your third-parties (with Eigen third party)
• Press Configure -> Generate.
• Open generated solution and check that all toolkits contain path to the Eigen header file if toolkit properties (Additional Include Directories).
• Add some code with usage of Eigen third party (include an Eigen header file and use some Eigen class).
• Check usage of HAVE_EIGEN preprocessor definition.
• Compile the solution.

0028197: Support of the "Eigen" third party
Supporting of "Eigen" third party was added to CMake build procedure.
Dear ibs,
Supporting of "Eigen" third party was added to CMake build procedure.
It is possible to use both types of "Eigen" third party distribution - source code and installed by CMake.
To use Eigen third party in some toolkit it is necessary to add "CSF_EIGEN" line into EXTERNLIB file of the toolkit, after that you can use CMake ui variable "USE_EIGEN" during configuration.
As i understand there is no library to link to. Compiler must be able to find the Eigen header files.
If you are using Eigen third party, preprocessor definition HAVE_EIGEN will be created.
Example of usage of Eigen header file:
#include <Eigen/Dense>
Note that in case of using Eigen source code variable "3RDPARTY_EIGEN_DIR" will be equal to "3RDPARTY_EIGEN_INCLUDE_DIR" and this is OK.
Please review occt branch CR28197.
