Sorry sent too soon, finger slipped.
...
I have been giving wrong advice about the usage of CMAKE_FIND_ROOT_PATH
which seems to be "reserved" for cross-compiling whereas
CMAKE_PREFIX_PATH
CMAKE_INCLUDE_PATH
CMAKE_PROGRAM_PATH
CMAKE_LIBRARY_PATH
CMAKE_IGNORE_PATH
are meant to be used in the general case.
Could someone enlighten me about the intended usage and
relationship between those vars and their "SYSTEM" counterpart
CMAKE_SYSTEM_*_PATH ?
And may be why do we need CMAKE_FIND_ROOT_PATH for cross-compiling
if CMAKE_PREFIX_PATH already existed?
CMAKE_*_PATH are documented (through --help-variables)
whereas CMAKE_FIND_ROOT_PATH doesn't seem to be currently.
