Hello, I am trying to get Avogadroapp to build.

I have difficultly building this because I can't find the same software in Fedora so I can't steal spec file from them.
I do find a PKGBUILD on AUR.
Which I find the list of dependencies from.

CMake Error at avogadro/CMakeLists.txt:1 (find_package):
[   16s]   Could not find a package configuration file provided by "AvogadroLibs" with
[   16s]   any of the following names:
[   16s] 
[   16s]     AvogadroLibsConfig.cmake
[   16s]     avogadrolibs-config.cmake

[   16s]   Add the installation prefix of "AvogadroLibs" to CMAKE_PREFIX_PATH or set
[   16s]   "AvogadroLibs_DIR" to a directory containing one of the above files.  If
[   16s]   "AvogadroLibs" provides a separate development package or SDK, be sure it
[   16s]   has been installed.

I believe it is looking for AvogadroLibsConfig.cmake or avogadrolibs-config.cmake which it doesn't find.

Which I believe I have to use this build flag
-DAvogadroLibs_DIR=%{_prefix} \
but it does not work, likely that the directory to the libs are wrong, but I am not sure where or how to find out.
