Fails to build without "python" and "python3" symlink

Maybe call find_installation without arguments. See error log:

$ meson _build
[...]
Program python found: NO

src/meson.build:4:0: ERROR: python3 not found

This seems like it may be a meson bug? Calling find_installation without arguments would fail on systems where python2 is the default (do those still exist?), or where python2 is used to run meson (for whatever reason).

But I suppose I could make a fallback to work around this particular bug, e.g. of this form:

diff --git a/src/meson.build b/src/meson.build
index 2d386c6..93a1d52 100644

@haasn, 88dae4c5 doesn't help, see error log

I've tried. Works fine where python is a symlink to python2.7.

Program python3 found: YES (/usr/local/bin/python3.7)
...
[8/42] /usr/local/bin/python3.7 ../src/vulkan/utils_gen.py '' src/utils_gen.c
Found vk.xml: /usr/local/share/vulkan/registry/vk.xml

python2 is used to run meson (for whatever reason).

Not possible for years (if ever was).

Makes sense. In light of those two points I think it's fine for us to always use the version meson is using. Updated on master. Hopefully this time it works for you?

Thanks, builds fine.
