The full path to the compiler for LANG.

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'
