Add alternative meson install command
While installing meson using pip3 install --user meson, due to python path issues, build.ninja can't be located by ninja. meson generates ninja files fine, but then when you run ninja, it is unable to find meson's build.ninja python module due to path issues. It gives the following error on ninja -C build install: ninja: Entering directory `build' ninja: error: loading 'build.ninja': No such file or directory After uninstalling meson using pip3 and installing it again using pip without --user argument solved the issue. Add a troubleshooting section to the readme to describe this issue and suggest possible solutions.

+Several users have reported issues with meson installation, crux of the issue
+is a potential version mismatch between the version that root uses, and the
+version that the normal user uses. On calling `ninja -C build`, it can't find
+the build.ninja module. This is a snippet of the error message.
+ ninja: Entering directory `build'
+ ninja: error: loading 'build.ninja': No such file or directory
+This can be solved in two ways:
+1) Don't install meson again if it is already installed system-wide.
+2) If a version of meson which is different from the system-wide version is
+already installed, uninstall that meson using pip3, and install again without
+the --user argument.
