[PATCH] Fix typos Unsuported -> Unsupported (#180)

[PATCH] Fix typos Unsuported -> Unsupported (#180)

* Client builds fail at linking due to missing targets when
USE_SYSTEM_LIBRARY is true.

#For targets not using pkg-config... and USE_SYSTEM_{DEPENDENCY} is true eg. xdgutils \
#find_dependency needs to be used as when clients (aka appimagelauncher) try to use this library we get linking failure
#because the dependencies of the dependency(libappimnage) targets are not imported. Hope this makes sence.
#Builds fine in debian and appimagelauncher no longer has linking failures.

* Fix typos Unsuported -> Unsupported.

* Revert "Client builds fail at linking due to missing targets when"

This reverts commit fbbabbdcf3c466a506fbd6ec95d9e9a8c9f96830.
