Hi,
I've build a patch for BUG #6818
On build process of buildroot the toolchainfile.cmake is created, but
with wrong absolut path.
When shareing the toolchain or move the folder you get problems this
path settings.
A workarround for cmake files is
- get the path of the toolchainfile.cmake and set the the variables.
Regards
Uwe

this is the way Buildroot community works.
Anyway, I looked at the patch.

I found the part touching the package/Makefile.in a bit confusing.
The idea of what has to be done in the toolchainfile.cmake is good, though
I think you miss some $-escaping...

I didn't know how to contribute the right the way.
But for the next patches I will do it the right way.
Thanks!
