Help/variable/CMAKE_LANG_COMPILER.rst
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.
.. note::
With :ref:IDE Build Tool Generators, including
:ref:Visual Studio Generators and :generator:Xcode, this variable is
computed automatically and should not be set. Instead, specify a toolset
using :option:cmake -T.
Usage ^^^^^
With :ref:Command-Line Build Tool Generators 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
:option:-D <cmake -D> on the command line.
.. note:: Options that are required to make the compiler work correctly can be included as items in a list; they can not be changed.
.. code-block:: cmake
#set within user supplied toolchain file set(CMAKE_C_COMPILER /full/path/to/qcc --arg1 --arg2)
or
.. code-block:: console
$ cmake ... -DCMAKE_C_COMPILER='qcc;--arg1;--arg2'
