[Buildroot] [RFCv3 04/15] pkg-cmake: install CMake files as part of a package

[Yann E. MORIN <yann.morin.1998@free.fr>]

Thomas, All,

On 2017-12-01 21:53 +0100, Thomas Petazzoni spake thusly:
> Currently, the toolchainfile.cmake and Buildroot.cmake files are
> installed outside of any package, just triggered by the toolchain

What I am more concerned about, is that the cmake package is registering
a hook for another package, toolchain.

Have you tried to run check-package on that?

Yann E. MORIN.
