"""
This function loads the pkgInfo.py of each dependency package.
If environment settings are found there they will be loaded into
the environment of the current Python process.
Example:
The pkgInfo.py of Matlab states MATLAB_ROOT, PATH and
LD_LIBRARY_PATH settings in its pkgInfo.py. Before compiling
such variables must be set.
On Linux, alternatively, this can be achieved by sourcing the
BashSrc files. Nevertheless this is not possible in all cases
(especially Matlab because multiple versions are available)
when used within CIA.
With some modifications this setEnv() approach conceptually
potentially could also work on Windows.
Attention: This function should only be called once (at least not
repeatedly when compiling the same package again from
within Python) to not unnecessarily increase the length
of PATH, LD_LIBRARY_PATH etc.
