/*
|
|
For testing purposes, we define a static global variable here in a function that each individual
|
|
test .cpp calls with its initialization lambda. It's convenient here because we can just not
|
|
compile some test files to disable/ignore some of the test code.
|
|
|
|
It is NOT recommended as a way to use pybind11 in practice, however: the initialization order will
|
|
be essentially random, which is okay for our test scripts (there are no dependencies between the
|
|
individual pybind11 test .cpp files), but most likely not what you want when using pybind11
|
|
productively.
|
|
|
|
Instead, see the "How can I reduce the build time?" question in the "Frequently asked questions"
|
|
section of the documentation for good practice on splitting binding code over multiple files.
