# We need a *third* `FindPython`-style call in this codebase because the host
|
|
# `Python3_EXECUTABLE` may not have pybind11 and cxxheaderparser installed,
|
|
# and installing it can be onerous. To work around this problem we try to detect
|
|
# whether the host interpreter has the necessary dependencies first, and if it
|
|
# does not, fall back to using `uv`.
