This is not the way you do it.

Homebrew’s `gettext` formula [is intentionally keg-only because it would otherwise conflict with stock MacOS software](https://github.com/Homebrew/homebrew-core/blob/master/Formula/gettext.rb#L14-L15):

> ```
> $ brew info gettext
> <...>
> ==> Caveats
> gettext is keg-only, which means it was not symlinked into /usr/local,
> because macOS provides the BSD gettext library & some software gets confused if both are in the library path.
> 
> If you need to have gettext first in your PATH run:
> echo 'export PATH="/usr/local/opt/gettext/bin:$PATH"' >> ~/.bash_profile
> 
> For compilers to find gettext you may need to set:
> export LDFLAGS="-L/usr/local/opt/gettext/lib"
> export CPPFLAGS="-I/usr/local/opt/gettext/include"
> 
> ```

CMake honors these envvars when configuring the compiler.
