| # CMake package infrastructure |
| # |
| # This file implements an infrastructure that eases development of |
| # package .mk files for CMake packages. It should be used for all |
| # packages that use CMake as their build system. |
| # |
| # See the Buildroot documentation for details on the usage of this |
| # infrastructure |
| # |
| # In terms of implementation, this CMake infrastructure requires |
| # the .mk file to only specify metadata information about the |
| # package: name, version, download URL, etc. |
| # |
| # We still allow the package .mk file to override what the different |
| # steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is |
| # already defined, it is used as the list of commands to perform to |
| # build the package, instead of the default CMake behaviour. The |
| # package can also define some post operation hooks. |
