Wrong output from meson

[vdweide]

Describe the bug
When I run the meson script for building it gives the wrong build command. This is both for the master and develop version.

To Reproduce
Simply type
./meson.py build

One of the last output lines is
Use './ninja -C false install' to compile and install SU2

while it should be
Use './ninja -C build install' to compile and install SU2

Desktop (please complete the following information):

• OS: Ubuntu 18.04
• C++ compiler and version: GCC 8.4.0
• MPI implementation and version: Sequential
• SU2 Version: 7.0.5

My fault, I'll fix it.

Looks like this one is solved, right?

Yup, I thought the PR would close it automatically.
