ConfigFile::excludeFileFromSystem() is returning relative path to etc dir on FreeBSD

[tuaris]

I am upgrading the owncloudclient FreeBSD port from v2.6.0 to v2.7.4 and I am receiving an error saying ownCloud "Could not read system exclude file".

Expected behavior

ConfigFile::excludeFileFromSystem() should return /usr/local/etc/ownCloud

Actual behavior

ConfigFile::excludeFileFromSystem() is returning etc/ownCloud

Steps to reproduce

1. Build and install client v 2.7.4
2. Launch
3. Observe error

Client configuration

Client version: 2.7.4

Operating system: FreeBSD

OS language: English

Ktrace shows that it is resolving to a relative path:

Here is a ktrace for v2.6.0 showing the path is being resolved correctly

I was able to work around the problem by passing -DSYSCONF_INSTALL_DIR="${PREFIX}/etc" to the cmake args. (where PREFIX is an env usually set to /usr/local).

This wasn't necessary in any previous versions, but it's fine if it required going forward.
