that *sort of* sounds like what is happening, but to be pedantic,
it's not that cmake can't find binaries in hosttools, it's that
*other* packages can't locate cmake on the host even after setting
ASSUME_PROVIDED += "cmake-native"
i am assuming that whatever search path is used for "native" tools is
extended by the use of ASSUME_PROVIDED -- is that what your patch is
addressing? in any event, i've now run into a couple other packages
with the same issue -- "cmake: command not found" -- libcomps-native
and librepo-native, so i'll just ASSUME_PROVIDED them too for the
moment, as they're both installed on my host.
