[CMake] Cross compilation question

[Steven Wilson]

In my CMake configuration files I have something like the following:


if(SYSTEM STREQUAL "iOS")
    set(CMAKE_C_COMPILER "foo" CACHE STRING "message" FORCE)
    set(CMAKE_CXX_COMPILER "bar" CACHE STRING "message" FORCE)
endif(SYSTEM STREQUAL "iOS")

Then when configuring the system I pass -DSYSTEM:STRING=iOS on the command
line (or through a GUI).

For my iOS system I use the makefile generator.
