Accessing the docs at http://modwsgi.readthedocs.io/en/develop/release-notes/version-4.5.12.html should help you.
In short:
By default, the installation looks for Apache in C:\Apache24 , C:\Apache22 and C:\Apache2 , since your installation is none of this, you need to set the environment variable MOD_WSGI_APACHE_ROOTDIR to the path to which you installed it.
On your system, you will do this by running this on the command line:
set "MOD_WSGI_APACHE_ROOTDIR=F:\Apache24"
Which sets the variable, and then you can run the pip command (on the same command line):
pip install mod_wsgi
For more information on the set command, run the set /? Command on the command line.
