Subject: [PATCH] CMakeDetermineSystem: use oe environment vars to load default
toolchain file in sdk
Passing the toolchain by:
- shell aliases does not work if cmake is called by a script
- unconditionally by a wrapper script causes cmake to believe it is
configuring things when it is not (for example, `cmake --build` breaks).
The OE_CMAKE_TOOLCHAIN_FILE variable is only used as a default if no
toolchain is explicitly specified.
Setting the CMAKE_TOOLCHAIN_FILE cmake variable is marked as cached
because '-D' options are cache entries themselves.
Upstream-Status: Inappropriate [oe-core specific]
