ViSP core module may use several optional third-party libraries which are: OpenCV, eigen, lapack and pthread.

eigen	++	++	++	Matrix pseudo-inversion
lapack	++	++	++	Matrix pseudo-inversion
pthread	++	++	++	Code optimisation

Other optional 3rd parties

The following table shows the capabilities that could be obtained with the other optional 3rd party libraries.

Yarp	+	+	+	Image wrapper
GSL	+	+	+	Matrix pseudo-inversion (useful only if lapack not installed)

Deprecated optional 3rd parties

After releasing ViSP 3.2.0 we introduce pugixml as a built-in 3rd party library. It replaces favorbly libxml2 3rd party library. As a consequence, there is no more need to install any 3rd party to parse xml files.

For those who want to continue to use ViSP releases up to ViSP 3.2.0 included, we give the instructions to install libxml2:

3rd party				Capabilities
libxml2	++	++	++	XML parsers
