Description Paul Menzel 2017-07-21 14:20:55 UTC 
Using Cmake to build Apache HTTPD 2.4.27, it fails with the error below.

```
$ cmake -DCMAKE_INSTALL_PREFIX=/project/webmail2/20170721 /dev/shm/bee-webmail/httpd/httpd-2.4.27-0/source

I believe that’s the wrong path to look at. The `PREFIX` should only matter where to install the built files, and not where headers are to be looked for.

Using Autotools works fine.

```
