Subject: [PATCH] BLD: add option to specify numpy header location
|
|
|
|
In some cases the numpy module might not be usable during build-time,
|
|
especially when cross-compiling. (E.g. when compiling for arm32 on a
|
|
x86-64 machine, the arm32 module is not usable at build time).
|
|
|
|
This makes meson fail, as it isn't able to figure out the location of
|
|
numpy headers.
|
|
|
|
To allow an alternative way to find these headers, introduce a meson
|
|
build option, where the location of the numpy headers can be specified.
|
|
|
|
In case numpy module cannot be loaded for some reason to query the
|
|
include folder location, fall back to the value of this meson option.
|
|
