/*
* Define ZES_ENABLE_SYSMAN=1 early so that the LevelZero backend gets Sysman enabled.
*
* Only if the levelzero was enabled in this build so that we don't enable sysman
* for external levelzero users when hwloc doesn't need it. If somebody ever loads
* an external levelzero plugin in a hwloc library built without levelzero (unlikely),
* he may have to manually set ZES_ENABLE_SYSMAN=1.
*
* Use the constructor if supported and/or the Windows DllMain callback.
* Do it in the main hwloc library instead of the levelzero component because
* the latter could be loaded later as a plugin.
*
* L0 seems to be using getenv() to check this variable on Windows
* (at least in the Intel Compute-Runtime of March 2021),
* so use putenv() to set the variable.
* but setenv() doesn't seem to exist on Windows, hence use putenv() to set the variable.
*
* For the record, Get/SetEnvironmentVariable() is not exactly the same as getenv/putenv():
* - getenv() doesn't see what was set with SetEnvironmentVariable()
* - GetEnvironmentVariable() doesn't see putenv() in cygwin (while it does in MSVC and MinGW).
* Hence, if L0 ever switches from getenv() to GetEnvironmentVariable(),
* it will break in cygwin, we'll have to use both putenv() and SetEnvironmentVariable().
* Hopefully L0 will be provide a way to enable Sysman without env vars before it happens.
