Some of the CI-Linux-Distros jobs failed because of this. Python3 is not
available by default on Debian:9 nor in Centos:8.
Since we are not currently running the tests in those platforms, and
python3 is just used for testing, we do not want to enforce this project
dependency.
0.9.1 remains broken regardless and is beyond fixing in this place.
Build-tested with both libssh 0.9.0 and 0.9.2.
Solution copied from KDE's kio-extras commit 24506c2af8d1904a99538543804306c6c2b81ca2
- Integration tests had to be disabled with 2012 and 2013. There were
few (4) tests failing for these cases.
- Only bring libiconv with conan when a windows subsystem is detected.
- libiconv can be enabled now with a conan option.
- Use infinity instead of INFINITY
- Use conan_basic_setup(). Fixes a problem with gtest is VS2012
- call vcvarsall.bat for each compiler version so that nmake can be
found.
