The full path to the compiler for
This is the command that will be used as the
<LANG> compiler. Once
set, you can not change this variable.
This variable can be set by the user during the first time a build tree is configured.
If a non-full path value is supplied then CMake will resolve the full path of the compiler.
The variable could be set in a user supplied toolchain file or via -D on the command line.
Options that are required to make the compiler work correctly can be included as items in a list; they can not be changed.
#set within user supplied toolchain file set(CMAKE_C_COMPILER /full/path/to/qcc --arg1 --arg2)
$ cmake ... -DCMAKE_C_COMPILER='qcc;--arg1;--arg2'
