The eigen package was introduced as a generic package, but upstream was in fact using CMake. The motivation of this change is to fix package detection with CMake. Eigen3 library normally installs a signature file named "signature_of_eigen3_matrix_library" to help library detection: https://gitlab.com/libeigen/eigen/-/blob/3.3.7/CMakeLists.txt#L423 The library also provide a CMake macro that use this file to detect it: https://gitlab.com/libeigen/eigen/-/blob/3.3.7/cmake/FindEigen3.cmake#L76 Without the signature file installed, packages searching for this library with this method will fail. Other packages usings pkg-config are not affected by this issue. By using the cmake-package infrastructure, all the needed files are now installed, fixing this CMake detection issue. Other changes in this patch: - Updated the Eigen git repository to the new url: https://gitlab.com/libeigen/eigen - Removed all build and install staging commands (now included in upstream cmake) - Package needs EIGEN_SUPPORTS_IN_SOURCE_BUILD = NO - Removed the BR2_PACKAGE_EIGEN_UNSUPPORTED_MODULES option, as this option is not proposed by the upstream CMake. Unsupported module header files are now unconditionally installed. As such, no need to introduce a legacy entry for BR2_PACKAGE_EIGEN_UNSUPPORTED_MODULES: users that had it enabled will still get the files installed, while those that did not will get them installed now. - Updated hash for source package, because the first component in the stored paths changed from eigen-eigen-323c052e1731/ to eigen-3.3.7/ and some mercurial related files (.hg_archival.txt, .hgtags) got dropped after the conversion to git. - Reformat hash file with two spaces delimiters - Define EIGEN_CONF_OPTS to set pkg-config .pc install path Signed-off-by: Julien Olivain <juju@cotds.org> Tested-by: Matthew Weber <matthew.weber@rockwellcollins.com> Signed-off-by: Yann E.
