Problem description

When using scons sphinx_docs options while building Cantera the scons configuration error arise:

scons: Reading SConscript files ...
SCons 4.9.1 is using the following Python interpreter:
    /usr/bin/python3.12 (Python 3.12)
INFO: Building Cantera from git commit '3f2057c6b'
NameError: name 'windows_options_full' is not defined:
  File "/home/sorath/Downloads/packages/cantera_test/cantera_docs/cantera/SConstruct", line 986:
    config_full.add(windows_options_full)

Steps to reproduce

1. Clone Cantera's github repo git clone https://github.com/Cantera/cantera.git
2. Change directory to ./cantera/
3. Try to run build process, e.g. with command scons -j4 build debug="no" f90_interface=y python_package=y python_cmd=python3.13 system_blas_lapack=n optimize_flags="-Wno-inline" renamed_shared_libraries="no" use_pch="no" system_fmt="y" system_sundials="y" system_eigen="y" system_yamlcpp="y" env_vars="all" extra_inc_dirs="/usr/include/eigen3" prefix="/usr" doxygen_doc=yes sphinx_docs=y.
   Please notice that sphinx_docs=y option is used at the end of command (or sphinx_docs=True if prefer).

Additional context

It seems the broken changes were introduced in commit 97c2b6c and now windows_options_full and config_options_full aren't defined because sphinx wasn't in COMMAND_LINE_TARGETS (i.e. scons sphinx command wasn't called).
