Error building

[MarcelRobitaille]

I just cloned this repo and got this error doing sudo make install.

meson build
Directory already configured.

Just run your build command (e.g. ninja) and Meson will regenerate as necessary.
If ninja fails, run "ninja reconfigure" or "meson --reconfigure"
to force Meson to regenerate.

If build failures persist, run "meson setup --wipe" to rebuild from scratch
using the same options as passed when configuring the build.
To change option values, run "meson configure" instead.

I was able to solve this by adding a virtual default destructor to Intercept:

class Intercept {
public:
  virtual ~Intercept() = default;
...
