- ``tools.build:compiler_executables`` (new in version 1.55) dict-like Python object which specifies the compiler as key
and the compiler executable path as value. Those keys will be mapped as follows:

* ``asm``: will set ``CCAS`` in *conanautotoolstoolchain.sh|bat* script.
* ``c``: will set ``CC`` in *conanautotoolstoolchain.sh|bat* script.
* ``cpp``: will set ``CXX`` in *conanautotoolstoolchain.sh|bat* script.
* ``cuda``: will set ``NVCC`` in *conanautotoolstoolchain.sh|bat* script.
* ``fortran``: will set ``FC`` in *conanautotoolstoolchain.sh|bat* script.

Moreover if build machine is Windows and values are paths, they will be curated during this mapping
(ie converted to unix path, and spaces removed if possible by converting folders to short names).
