Hi,
couldn't we just do it like this?
PACKAGECONFIG ?= ""
PACKAGECONFIG[optviewer] =
"-DLLVM_HAVE_OPT_VIEWER_MODULES=ON,-DLLVM_HAVE_OPT_VIEWER_MODULES=OFF,,python3-pygments
python3-pyyaml"
Depending on wether the PACKAGECONFIG option is taken it looks like this
in CMakeCache.txt:
//No help, variable specified on the command line.
LLVM_HAVE_OPT_VIEWER_MODULES:UNINITIALIZED=OFF
//No help, variable specified on the command line.
LLVM_HAVE_OPT_VIEWER_MODULES:UNINITIALIZED=ON
Have you test it? The config-ix.cmake file sets the
LLVM_HAVE_OPT_VIEWER_MODULES variable [1].
Instead of LLVM_HAVE_OPT_VIEWER_MODULES I would set PY_PYGMENTS_FOUND,
PY_PYGMENTS_LEXERS_C_CPP_FOUND and PY_YAML_FOUND.

There is a reproducibility issue which shouldn't be too hard to fix if
someone had a few minutes to help out:

It is in llvm and is a cmake configuration issue. Rather than setting
that option based on the presence of python modules (with python from
the host), we should add a configuration option to force it to be
disabled in our case. Should be upstreamable with the right patch.
I'm not able to test it at the moment but it should be possible to set
the variables (PY_PYGMENTS_FOUND, PY_PYGMENTS_LEXERS_C_CPP_FOUND and
PY_YAML_FOUND) to OFF via EXTRA_OECMAKE:
-DPY_PYGMENTS_FOUND=OFF
The find_python_module function in config-ix.cmake returns early if
the variable PY_${module_upper}_FOUND is defined.
