This would generate a second set of the 
CMAKE_FIND_ROOT_PATH_MODE_PROGRAM with a different value.

Why not add a new variable and use it in the existing set:

+OECMAKE_FIND_ROOT_PATH_MODE_PROGRAM = "ONLY"
+OECMAKE_FIND_ROOT_PATH_MODE_PROGRAM_class-native = "BOTH"

-set( CMAKE_FIND_ROOT_PATH_MODE_PROGRAM ONLY )
+set( CMAKE_FIND_ROOT_PATH_MODE_PROGRAM 
${OECMAKE_FIND_ROOT_PATH_MODE_PROGRAM})
